"Use fighter planes to guide?" Wang Xuexin's words shocked Professor Su: "Can this be done?"
Su Xin also said in surprise: "Can you still do this?"
In fact, it was not just them, everyone here found it incredible that Wang Xuexin said that there are still people in this world who use fighter planes to guide missiles to hit warships!
But this is a common thing for Wang Xuexin... In fact, it cannot be said to be "commonplace", because Wang Xuexin has never seen it, he just knows these theories.
Wang Xuexin thought for a while and then asked: "Have you ever heard of television?"
"certainly!"
"I've seen it too!"
…
Television was invented in 25 years. Although it was not yet popular in China at this time, it was already quite mature in the West. Researchers who have studied abroad all know about this thing.
Wang Xuexin said: "The simplest way is to use the principle of television for guidance. We install a camera in front of the missile. The camera takes a picture of the scene ahead and transmits it to the aircraft through a radio signal for imaging, so the pilot can control the missile based on the image he sees.
Make it hit the target!"
Everyone couldn't help but suddenly understood. After being silent for a while, everyone immediately became excited:
"This method is good and it is not difficult to implement!"
"Yes, it doesn't require much money!"
"We can even use off-the-shelf cameras and televisions!"
…
There is nothing wrong with these words. Technically speaking, this guidance method is almost not difficult. It can even be done easily in another country. The difficulty lies in being able to think of this method.
In fact, Hans had thought that the HS293D they developed was the first TV-guided bomb, but the successful test launch was only in August of this year, that is, a few months later.
The disadvantage of this guidance method is that it cannot achieve "launch and forget", that is, the pilot must pay close attention to the missile from the moment it is launched until it hits the target, and it also depends on how it feels when it hits the target.
The most deadly thing is that this guidance method uses wireless signals to communicate, so it is easy to interfere once the enemy knows it.
To this end, Hans had to convert wireless communication into wired communication, that is, use a long wire to connect the bomb to control it, so that it would not be interfered by the enemy.
There is a reason why Wang Xuexin chose this guidance method.
He also wants to develop Gaul's "Flying Fish" anti-ship missile in one go. This thing can be mounted on an aircraft and launched, and it can also be "fired and forgotten"... Missiles that can achieve "fired and forgotten" are all
The missile is equipped with a radar that can seek independently.
However, given the production conditions of the Eighth Route Army at this time, to be precise, the current level of transistor computers cannot reach this level.
Wang Xuexin has also thought about passive guidance, such as radar locking on enemy warships to indicate targets for "high fire", and a more advanced point is to use lasers to lock on targets... Using lasers to indicate targets is not easy to be interfered with.
But to do this, it is necessary to install a relatively complex receiving device and a computer control system for calculation in the "high fire", which cannot be achieved in a short time.
Therefore, Wang Xuexin plans to take it step by step, starting with something simple.
And to say the least, the situation of the Eighth Route Army at this time should be more suitable for television guidance.
First of all, the speed of "high fire" is relatively slow, no more than 300 to 400 kilometers per hour. This speed gives the pilot enough time to react... If the speed is too fast, the missile will pass by with a "swish" before the pilot has time to control the missile.
It's already passed.
The second thing is that there is no such technology at this time. Hans has similar technology, but it uses radio to control the bomb.
There is no such equipment on the Chinese battlefield, so the Japanese do not know how to interfere with this guidance method.
only……
Wang Xuexin couldn't help but frowned as he thought about it.
Su Xin saw something wrong with Wang Xuexin's expression and asked in confusion: "What's wrong? Is there something wrong?"
The conference room also became quiet, and everyone turned their attention to Wang Xuexin.
Wang Xuexin didn't know what to say. He couldn't say that Hans was also researching this technology, so once the Eighth Route Army used this equipment on the battlefield, as long as it sank a few warships, the Japanese would immediately learn about this guidance from Hans.
Weaknesses of the method.
Once the Japanese know this, they only need to install radio jamming signals on the warships.
After thinking about it, Wang Xuexin said: "Comrades, there is a saying that 'people who have no long-term worries must have short-term worries.' Although we can indeed use TV control to achieve guidance, we cannot be satisfied with this status quo, because it has a very important problem.
Fatal flaw: extremely easy to be interfered with!”
Su Liguo nodded: "Indeed, unless the devils don't know, once they know... it will probably mean that our army's missiles will be completely ineffective! At that time, we will be back to the starting point again, and this is likely to cause problems on the battlefield.
Our army caused greater losses!"
Everyone nodded in agreement.
This is easy to understand. If our army did not have such guided missiles, the campaign to attack Fengtian would probably not have started.
But now our army has a guided missile plan that has been launched. In the early days, our army even used this missile to successfully destroy several Japanese warships to occupy coastal areas... At this time, if the Japanese implemented radio interference to make our missiles ineffective, then the warships
A large number of artillery shells will be poured on the heads of our soldiers.
"Then... what other guidance methods are there?" Professor Su asked.
"Laser!" Wang Xuexin said without thinking: "Laser guidance must be developed!"
The reason why Wang Xuexin talks about lasers is because if you use radio, you will still be interfered by the Japanese. It is better to develop lasers directly in one step.
"Laser?" Su Xin widened her eyes and asked in surprise, "Can lasers also be guided?"
"Let's put it this way!" Wang Xuexin replied: "If we install a laser emitting device on a fighter plane and continuously shine the laser on the enemy warship during war, the enemy warship will diffusely reflect the laser. If our missile is equipped with
The laser receiving device can measure the amount of received laser light, so you only need to keep the missile flying in the direction with the largest amount of received laser light!"
At this time, it was Chen Jiefeng who was the first to understand: "The direction with the largest amount of reception is actually the light source, which is the Japanese warship!"
Wang Xuexin nodded.
The characteristic of laser is that it is highly concentrated, so when it is launched from a fighter plane, it will not be received by missiles, but it is different when it hits a warship... The rough surface of a warship will reflect in all directions, and of course this includes missiles.
direction.
Therefore, the missile cannot miss as long as it heads towards the "light source" of the warship.
This is actually what modern times call passive guided missiles.
