The biggest problem with space targets is not "interception" but "interception" and basic work".

Alert, discover that tracking and locking are the four most complex, most important and most difficult stages in the entire interception process. Relatively speaking, the final "interception" is often called destroying, but it is the easiest stage to achieve in the entire interception process.

The biggest difference between an interceptor satellite and an interceptor missile is the "visiting" section.

When the ballistic missile is in the boost section, that is, the active section, the rocket engine is in the working state. The infrared and ultraviolet radiation released are very obvious, and it is easily discovered and identified by far-infrared detection equipment and ultraviolet detection equipment. Satellites operate in space basically rely on inertia and do not require additional power. Only use small orbit change rocket engines when changing or adjusting orbits, so it is difficult to be discovered by optoelectronic equipment. In this way, the warning system for satellites can only rely on radar, and is a high-precision radar.

In the early years of the Strength and the early years of the Strength century, radars for detecting space targets were deployed on the ground.

With technological advancements and reduced space launch costs, major powers led by the Republic and the United States have taken the lead in deploying so-called "missile alert radar satellites in space."

Everyone knows that if it is only targeted at ballistic missiles, there is no need to use radar satellites.

After having a warning system, there must be a discovery and identification system.

Simply put, the alert system is only responsible for wide-area dialing, and its main task is to determine the general orientation of the target; the main task of the discovery and identification system is to accurately judge the orientation of the target and determine the nature of the target. Because in the interception system for satellites, the work burden of the alert system is not heavy, the Republic and the United States combine the alert system with the discovery system seed. However, in the interception system for ballistic missiles, the alert system needs to work for a long time, while the discovery and identification system starts working after receiving the alarm. Therefore, it must be deployed separately to reduce the cost of daily use.

Relatively speaking, the screening is more difficult.

Because more and more countries are mastering aerospace technology, more and more satellites working in orbit and scrapped satellites, how to determine the nature of the satellite has become the top priority. According to data released by the International Aerospace Organization, the total number of artificial spacecraft in orbit at the end of the year exceeded the space waste between thugs and tens of millions of cubic meters. Although the main intention of the report is to remind all space powers that the sharp increase in space waste in the outer space of the earth has posed a serious threat to the peaceful use of outer space, the report also reflects the huge difficulty of intercepting satellites. Simply put, it is by no means easy to find the real target from the nearly ten thousand goals and determine its nature.

It is obviously not realistic to wait until the war breaks out before looking for enemy satellites.

The only way is to grasp the orbit of the enemy satellite in peacetime.

In fact, countries such as the Republic, the United States, Russia, and France that have intercepting satellite capabilities are doing this.

The Republic's Heavenly Soldier has a professional unit called "Star Map", whose main task is to monitor all satellites of hostile countries in peacetime. Because most military satellites have the ability to change orbits. Before or during wars, hostile countries are likely to allow military satellites to change orbits. Therefore, if you want to always grasp the orbit of the military satellites of hostile countries, you must achieve "real-time monitoring" and set up observation points globally. The ideal method is to deploy detection systems around the world according to the dialing range of the ground-based detection radar, according to the standards of the Republic's Heavenly Soldiers, at least a set of ground-based detection systems must be deployed globally. Influenced by politics, diplomacy, military, etc., no country can deploy ground-based detection systems worldwide. Therefore, the Republic spent huge amounts of funds to build two "ocean space surveying and mapping ships" for the heavenly soldiers. And invest huge funds to develop space exploration systems.

The rewards of huge investments are also huge.

Before the outbreak of the Japanese War, the Republic established a complete satellite tracking system. The "Star Map. Forces not only can grasp the operation of the hostile country's in orbit Wei Yan in real time, but also established a "constellation map system". Relying on the working conditions of the in-orbit satellite recorded by the system, it can easily find the real-time location of any satellite. When needed, you can quickly judge the nature of the target based on the "constellation map system" and the latest mastery.

After determining the nature of the target, you must follow up.

Unlike attacking targets on the ground, sea, and air, even in low-Earth orbit, hundreds of kilometers away from the ground, far-Earth orbit, sun-synchronous orbit, geosynchronous orbit, satellites on the earth-synchronous orbit are thousands of kilometers away from the ground, or even tens of thousands of kilometers. Any anti-satellite system cannot cover the entire outer space. There are tens of seconds to hundreds of seconds between the distance from discovering the target and finally destroying the target. Because satellites fly at the first cosmic speed of 7 kilometers per second, even a few seconds interval means that the target flies several kilometers. Compared with this distance, the size of the satellite itself is negligible. In this way, the target must be continuously tracked before attacking.

Before the Japanese War, tracking satellites was not a troublesome. The main reason was that the orbits of satellites were relatively fixed. Even military satellites with orbital change capabilities were very limited, and only the orbits needed would change the orbit just a moment. Generally, they would fly on fixed orbits.

After the Japanese War, countries paid more attention to the orbit change capability of satellites, because with limited defense means, improving the orbit change capability of satellites is the only way to improve satellite survivability. After the Republic and the United States began to establish a detection system for standard satellites for all countries, they often changed the orbit of satellites. Especially outside the surveillance range of the detection systems of hostile countries, changing the orbit of satellites has become an important means to improve satellite survivability. In this way, tracking satellites becomes more troublesome.

Relatively speaking, combined with the alert, discovery and identification system, it is still not very difficult to track satellites.

After the tracking is completed, the locking stage before the attack is set.

Compared with the tracking stage, the locking stage has higher requirements for detection accuracy. Before the detection accuracy is sufficient to meet the requirements of "precision strike", the measures adopted by various countries are very "barbaric", such as using anti-satellite missiles or anti-satellite satellites carrying nuclear warheads to detonate nuclear warheads near the target, destroying all satellites within a radius of hundreds of kilometers or even hundreds of kilometers, thereby achieving the goal of destroying the target. With the increasing number of satellites and the outer space becoming more and more crowded, such "barbarous" means are definitely not applicable. More importantly, after the Japanese war, major countries successively included military satellite systems in the category of "strategic facilities". Even if accidental injuries are caused, they may lead to catastrophic consequences.

The inability to use "barbaric" means can only improve the strike accuracy.

To improve the strike accuracy, the detection accuracy of the locking stage must be improved.

There are only three main weapons of anti-satellites, namely fragmented weapons, kinetic energy weapons and energy weapons. After explosion, fragmented weapons will form a large amount of space garbage, threatening their own satellites. They have been eliminated by major powers. Including the Republic, all focus has been shifted to kinetic energy weapons and energy weapons. Relatively speaking, energy weapons are more "clean" and will not generate much space garbage in the process of destroying satellites, and are more "popular".

Whether it is walking energy weapons or energy weapons, there are very high requirements for strike accuracy.

Taking kinetic energy weapons as an example, even if the kinetic energy warheads made by Ji Weihao and Jin were used, the radial area of ​​the warhead was increased by hundreds of times before attacking the target, and its actual coverage was only hundreds of square meters. In the vast outer space, this area was nothing. If the radial cross-section of the interceptor was circular, the attack progress must be controlled within the old meters. Obviously, for intercepting satellites that were tens of kilometers or even hundreds of kilometers away, the navigation accuracy of the old meters must be a major problem today.

In fact, among anti-satellite weapons systems, the most expensive is the detection and positioning system in the locking stage.

According to the calculation of the kinetic energy weapon interception system invested and developed by the Republic Tianbing, the detection and determination system in the locking stage account for about the ship's cost of the entire system. With the navigation system, these electronic devices alone account for about the total cost. It is also true that the development potential of the kinetic energy weapon interception system is far less than that of the energy weapon interception system. Because the energy weapon interception system does not require navigation equipment.

Of course, this does not mean that the energy weapon interception system does not require high locking accuracy.

In fact, the energy weapon interception system has much higher requirements for locking accuracy than the kinetic energy weapon interception system.

Due to the mass limitation of the carrier platform, that is, the interceptor satellite, the output energy of the space-based energy weapon interceptor system is definitely not as good as that of the ground-based and air-based interceptor systems. In order to destroy the target with limited output energy, the space-based energy weapon interceptor system adopts many unique designs. For example, the interceptor satellite developed by the Republic is equipped with a mirror with a diameter exceeding the thug and a meter-deepening meter-made frame made of memory alloy. The coating composite material makes a mirror, and the attack constellation consists of otter "sister satellites" to secondary focus the laser beam and increase the energy density when the laser beam illuminates the target. The United States uses the "three-inverse focus technology" on the space-based energy weapon interceptor satellite to achieve the same goal. No matter what technology is used, the ultimate goal is to increase the energy density when the energy weapon illuminates the target.

This involves the issue of energy scattering.

Although lasers are the best directivity light source that humans can find so far, lasers are not extremely parallel light rays, but their directivity exceeds other light sources. The ratio of the radius of the scattering spot to the illumination distance of lasers of different wavelengths is between one ten thousandth and one hundred thousandth. That is to say, the range is between four meters of the thug. Because the light energy of the laser beam can be regarded as evenly distributed, the attenuation speed of the energy is proportional to the square of the range.

Use energy weapons to block satellites, with a range of more than hundreds of kilometers.

In this way, even if the laser weapon with the best directionality has a range of 1,000 meters, the energy utilization rate is only 0.

Even if the direction of energy weapons can be improved through various technical means, for example, after the use of reflectors, the directionality of the space-based laser interceptor in the Republic can be increased by at least an order of magnitude. When the range is a thug and kiss a thousand meters, the energy utilization rate is only 3. In other words, the locking accuracy of the energy weapon intercept system must still be controlled within the old meters. If the range continues to increase, the locking accuracy must be further improved.

It can be said that the lock is a critical issue that restricts the rapid development of the energy weapon interception system.

The Republic has repeatedly pushed the construction of the fourth stage of the national strategic defense system. The fundamental reason is that the development speed of the energy weapon interception system is far from the expected goal. According to the idea of ​​deploying laser interception satellites proposed by Tianbing, the average interception distance of military satellites in enemy countries is more than kilometers. If the laser output power cannot be increased and the directionality problem can be solved, the locking accuracy must be increased to less than 2 meters to meet the basic needs of the interception target.

It can be seen from this that the difficulty of developing a space-based interception system is far beyond the imagination of ordinary people.

In fact, the early development of the heavenly soldiers has many similarities with the early development of the air force. It took nearly half a century to become the military force that dominates the war. It not only took nearly half a century, but also experienced many technological revolutions. In other words, if there is no turbine engine, the aircraft is at most the main force of war, not a dominant force; if there is no precise strike weapon, the aircraft is at most a destructive force, not a decisive force. If the heavenly soldiers want to replace the air force and become the dominant force of war, it is still a long way to go.

As one of the earliest heavenly soldiers established in the world, the heavenly soldiers of the Republic have been moving forward.

Compared with other types of war, space combat is faster.

Long before the outbreak of the war, the Republic's heavenly soldiers not only launched Lido military satellites urgently and established a small space-based satellite interception system for India, but also adopted a one-on-one approach to track and monitor many old military satellites in India, and were ready to strike at any time.

After receiving the order from the former Chanzhi Command, the Heavenly Warrior immediately launched an action.

Interception is not difficult when fully prepared.

At 4 o'clock, all preparations for the four stages before the attack were in place.

There was no warning, no sign. The attack began quietly.

Although the specific situation of this round of attacks has been locked in the top secret database of the Republic's Ministry of Defense. However, according to some surveillance data released by the Pentagon after the war, the Republic's Heavenly War used kinetic weapon interception systems and energy weapon interception systems in this round of attacks, but the frequency of kinetic energy weapon interception systems is higher. This is more difficult to deal with the technology of the energy weapon interception system. Various related technologies are not yet mature and have a big laugh system.

Later, the International Aerospace Organization also released some relevant data. Among the attacked satellites, old ones were completely destroyed, and only three were "paralyzed." It can be concluded that the number of combat operations of the energy weapon intercept system will not be less than three times, but it is not certain whether the Republic's space-based laser interceptor has the ability to completely destroy the target. If so, then the Republic's actual combat capability of the space-based interceptor system has been greatly improved, because the complete destruction of the target requires much more energy than the paralyzed target.

It can be seen that using energy weapon interception systems to deal with Indian military satellites has a great test smell, and the test port is not intercepting satellites, but intercepting ballistic missiles and missile warheads. If the Republic's heavenly soldiers use high-energy laser interceptors in this round of attack, then the Republic's space-based interception system has the ability to intercept ballistic missiles and missile warheads, because the key to intercepting missiles and warheads is not paralyzing, but destroying.

Regardless of the result, this round of interception was very successful.

More importantly, the Indian Air Force's military satellites are under the jurisdiction of the Air Force and do not know what happened.

Because satellites have a certain period of flight orbiting the earth, and India does not have many overseas military bases. The Republic's heavenly soldiers attacked India's military satellites after they left the sky above India's mainland, so the Indian Air Force would have to wait 4 hours at the earliest to know that its military satellites had been destroyed. Although the Indian Air Force would be alert as the military communication satellite "failed." However, failure of communication satellites is very common. For example, the abnormality of solar nuclear spans will have an impact on the ionosphere of the earth's atmosphere, so that the surface receiving stations cannot receive signals from communication satellites for the time being. If the Indian Air Force wants to determine whether the military satellite has been attacked, it must have more "evidence".

What war requires is not evidence, but opportunity.

This is exactly what Pei Chengyi wants.

The attack ends at 4 o'clock, and 4 hours later, that is, 8 o'clock.

If everything goes well, the large-scale bombing operation will begin at 8 o'clock. By then, even if the Indian Air Force reacts, the missiles and bombs will fall down. There is no time to organize resistance.

After receiving the combat report from the Heavenly Soldiers, Pei Chengyi still did not adjust his combat plan.

There is no need for this at all, and all actions are carried out according to the initial plan.

It was not until 6 o'clock that Pei Chengyi issued combat orders to combat troops at all levels. That is to say, from this time on, combat troops at all levels will act in accordance with the combat orders that have been issued, launching attacks before 8 o'clock, opening the prelude to the "strategic bombing".

While Pei Chengyi was waiting patiently at the front line command center, Wang Yuanqing was diplomatic in the rear

There must be sufficient reasons to start the war early.

Although Wang Yuanqing had "prepared" the reasons, the basic diplomatic work must be prepared in place, otherwise the Republic would not face the issue of war.
Chapter completed!
