Chapter 193: Technology that makes any air defense system meaningless!
The "opportunity to change the trajectory in an instant and avoid anti-missile interception" that Ding Hui mentioned was not an interceptor missile launched against the anti-missile system, but a trajectory change that was set before launch.
Even if there is no interceptor missile, it will definitely change course because it has been preset.
The reason lies in the calculation method.
The three-dimensional function trajectory correction made by Wang Hao is aimed at the '1-to-1' situation. '1-to-1' means that a fixed function changes its trajectory to another fixed function.
No matter what method is used to change the trajectory, the missile route after the trajectory change must be on a fixed function, so that it can be slowly corrected to the original trajectory based on the calculation results.
This is where the limitations come in.
Including real-time speed, height, direction, etc. must be set in advance to truly achieve one-to-one orbit change.
The one-to-one orbit change form is still very restrictive, but if you think about it carefully, you will know that the effect will still be quite amazing.
The vast majority of countries do not have a complete anti-missile system, or in other words, except for the top countries, no other country has a complete and complete anti-missile system.
The so-called perfect anti-missile system means that the entire process from the launch of the missile until it hits the target can be used for anti-missile interception.
The missile launch is divided into three stages in total, one is the ascent stage, the other is the middle stage, and the final stage, which is the acceleration stage, the midway stage and the re-entry strike stage.
In the first stage, the missile is usually launched from its own territory, and the interception range is not enough. In the second stage, the missile will be outside the atmosphere, which is a height that is difficult to reach.
Even with a complete anti-missile system, it is very difficult to intercept at these two stages.
In the third stage, the strike stage of re-entry into the atmosphere, the flight speed of ballistic missiles is very alarming, but it is also the main interception stage of ordinary air defense systems.
Most air defense systems are designed to target rapidly incoming missiles, mainly targeting interception within the atmosphere.
At the same time, the interception range is also limited.
For example, the famous Patriot system is a "low-level missile defense system" in the Amerikan air defense system. Its performance is still very strong, but the actual interception height is generally only within a range of thirty kilometers.
If the incoming missile can suddenly change its trajectory at an altitude of thirty kilometers, all the previous calculations of the air defense system will be useless, and even if the air defense missile is launched, it will not be able to hit the target.
It is also very difficult for the air defense system to lock the route of the incoming missile.
One is that it takes time.
The other reason is that ‘trajectory correction takes a certain amount of time’.
During the trajectory correction time, the trajectory of the missile is constantly changing, and it is impossible to achieve accurate calculations at all.
After the trajectory of the missile is modified, it may be very close to the concentrated target, and the time and space for interception will be lost.
"If we change the trajectory at an altitude of 30 to 40 kilometers and extend the trajectory change time, our conventional missiles can also break through most low-altitude anti-missile systems."
Ding Hui concluded excitedly, "Even if the opponent's anti-missile system can work, it may be necessary to launch three, four, or even more defense and control missiles to ensure effective interception."
After Ding Hui finished speaking, everyone in the office was very excited.
Zheng Guofeng's face turned red with excitement. Such technology was really amazing.
Conventional missiles only have conventional trajectories, which can be easily calculated by the anti-missile system, making it difficult to break through the air defense lock.
The cost of Qian Xuesen's ballistics is very high. Even if conventional missiles are used, it is difficult to continue until they hit the target, and they cannot achieve universal coverage.
Today's technology is different.
If this technology can be developed and matured, many series of missiles can be modified and equipped with this technical equipment to achieve strong penetration capabilities.
The most important among them are short- and medium-range missiles, because larger intercontinental missiles, or missiles that can achieve speeds of nearly Mach 20, do not need to change their trajectory to hit the target. As long as they are launched, they cannot be intercepted.
However, the above two missiles are not commonly used, and the cost is very high.
A technology that can achieve universal coverage on conventional missiles will become very valuable.
End of the meeting.
Everyone was discussing excitedly.
They are full of expectations for new technologies. Whenever they think of future conventional missiles that can directly penetrate the enemy's advanced anti-missile system, they feel excited and can't wait to see this technology.
The only one who wasn't excited was Pang Sibo. He didn't even know what was going on, but he heard such advanced technology.
"Is this imagining?"
Pang Sibo was still a little confused. He simply asked Zheng Guofeng, "Where does this high-end technology come from? Is it so powerful? It directly allows our conventional missiles to have the ability to change orbits?"
Zheng Guofeng looked at Pang Sibo with a smile, "It's the impossibility you said two days ago."
"ah?"
Pang Sibo was stunned for a moment, then mouthed two words, "Wang Hao?"
Zheng Guofeng nodded with a smile.
Pang Sibo was immediately surprised. He had discussed it with Zheng Guofeng before and just wanted to ask Wang Hao for advice. How come he came up with a solution?
And this solution is to directly achieve the trajectory change of conventional missiles?
It took the other party half a month to come up with a feasible method for orbit change calculation?
This is so amazing!
"No wonder the institute has always attached great importance to Ding Hui, the mathematician is really amazing!"
Pang Sibo felt very shocked when he thought about it, and then he also became excited. Being able to change the trajectory of conventional missiles can be said to have raised domestic missile technology to a higher level.
If the technology can really mature and spread to some ordinary missiles, it will be equivalent to upgrading all missiles.
What a big development this is?
It spans at least ten years, and even spans more than fifteen years!
This chapter is not finished yet, please click on the next page to continue reading the exciting content! He took a deep breath, and the more he thought about it, the more excited he became. It took him a long time to think of the real thing, "By the way, Professor Zheng, I'm sure this time
The date is set, Academician Zhao Xingli will be here on the 3rd of next month."
"At that time, other leaders from the third district will also come. They want to synthesize the existing high-end technologies and demonstrate the future research and development direction."
After hearing this, Zheng Guofeng immediately said indifferently, "What research direction are we talking about!"
"Isn't this the direction?"
"No matter what they argue, we must study this technology and complete it and perfect it!"
He stood up and said, "Everyone, be quiet! Be quiet!"
"Our next work is to understand all the mathematical logic of this data, and then work together to demonstrate how to implement it!"
"When people from the third district come next month, let them see the results of our work at Institute 137!"
"right!"
"Everyone, keep researching!"
Everyone became very positive.
Zheng Guofeng nodded with satisfaction, and then said to Pang Sibo, "By the way, also report Wang Hao's name. We can't be greedy for credit."
"That's for sure. When people from the third district come next month, just report it to them."
Pang Sibo nodded and said.
…
What can mathematics do?
There are so many things that mathematics can do.
Mathematics is inseparable from every field of application, and breakthroughs in mathematics can often lead to major breakthroughs in scientific foundations.
However, often top mathematicians do not pay attention to application fields, or even do not care about applications at all. They care more about theoretical research.
That may not be called attention, but rather a fascination with mathematical theory.
Wang Hao is like this.
The same is true for Luo Dayong.
They demonstrated the logical issues of complexity theory together, and they continued to study them for more than a week. They just sorted out the logical issues of the event, and they were able to enjoy it and indulge in it.
"N versus 1 is still a P problem, and it has not reached the level of NP."
"Theoretically speaking, this type of problem will always be solved one day. All we have to do is find simple methods."
"No matter how large the number of events is, it has an upper limit. Even if it takes 100 million times, counting from one to 100 million can still be completed."
"We start the analysis from the node. Event A is very complex and contains many events of the same type, but event B is fixed."
"Starting from commonalities is one way, but you can also think of other methods, such as setting a non-universal set and using a set to describe events."
"All A events correspond to B events, and the commonalities of A events are also very obvious. For example, they are all parameters of three-dimensional curve functions. There cannot be other functions. The difficulty lies in the uncertainty of the parameters."
"need……"
The two of them were constantly discussing, sometimes turning into arguments, or sometimes just thinking together in silence.
This has been going on for a week.
The working hours are more than ten hours a day, and there are constant discussions, arguments, and thinking. When I can't come up with a result, I even start to do weird things.
For example, Luo Dayong simply lay down on the table. He thought that this action might make the cerebral cortex more active, and he almost fell asleep.
Wang Hao stood by the window for a long time. He found that it was really interesting to think like this.
For example, he noticed that a bird's droppings almost fell on a student's head.
This has nothing to do with research, but occasionally letting your mind wander and distracting yourself can also give your brain a short rest.
"What would happen if the event analysis were reversed?" Luo Dayong suddenly proposed such a method.
Wang Hao continued to think, but he couldn't figure out the complicated logic.
Xu Jie came to deliver lunch to the two of them.
He put lunch on the table without disturbing their thoughts. Wang Hao and Luo Dayong continued to discuss.
At this time, Wang Hao suddenly said, "Xu Jie, don't move!"
"??"
Xu Jie was a little confused.
"You go to the wall and stand still, that's it." Wang Hao directed Xu Jie, observing again and again, and continued, "Can you stand on your head?"
"Handstand?"
"right."
Xu Jie hesitated for a long time, put his hands on the ground and asked, "Is that so?"
"Yes, can you get up?"
"certainly."
Xu Jie confidently used his hands to turn over and put his feet on the wall.
Wang Hao and Luo Dayong stood beside each other, pressing their chins and watching carefully.
Luo Dayong thought about it and said, "Just reversing it like this, logically equals the change of the end point and the origin."
Wang Haodao, "Not necessarily. Some logic will still follow the established rules, because the external influence is very large. You can see that his clothes still follow the rules of gravity and fall downwards, but his pants do not hang down. There are some incidents that have affected
External influences will not directly reverse the situation."
"Is such that."
Luo Dayong nodded thoughtfully, then walked to the whiteboard, took a pen and started writing, "Look at our research yesterday, there are several factors that will not be affected by inversion..."
They changed positions and continued the discussion.
Xu Jie continued to put his hands on the ground, holding it in until his face turned red. He didn't know if it was time to get up, and saw Chen Mengmeng coming in at the door.
Chen Mengmeng walked in on her feet. She turned to look at Xu Jie, feeling confused.
Xu Jie didn't want to embarrass himself in front of girls, so he was about to put his legs down when he saw Chen Mengmeng crossing his hands and making a 'stop' gesture.
Chen Mengmeng came over and whispered, "Wait a minute."
"do what?"
Chen Mengmeng took out her mobile phone and quickly pressed the camera button on Xu Jie while whispering, "I'll take two photos as a souvenir and send them to Moments."
Xu Jie quickly got down from the wall and gritted his teeth when he looked at Chen Mengmeng again.
This girl is so evil and rotten!
But because he was worried about disturbing Wang Hao and Luo Dayong's discussion, he still didn't make a fuss on the spot and could only walk out. As a result, Chen Mengmeng had already shared interesting stories with other people.

"..."
Until the end, Wang Hao and Luo Dayong still could not solve the problem.
Wang Hao felt that there was only one last chance left to solve the computational logic problem, but he couldn't find any inspiration.
Then I looked at the time and decided to give a lecture to the students.
"I'll explain the problem to the students and maybe they can figure it out."
He said so.
Luo Dayong was completely confused after hearing this.
The content of the small class that day turned into the event analysis problem of complexity theory. This problem made not only graduate students, but also doctoral students and professors dizzy.
Fortunately, Wang Hao explained it very seriously and clarified the logic in the middle.
Everyone can still barely understand it.
"This is a time logic analysis problem. We have thought of a good way, which is to invert cause and effect, but inversion of cause and effect will cause new problems. Some events will not be completely transformed due to inversion of cause and effect."
"Because there are external influences."
"Many factors correspond to one factor. The logic of the event is the Px1 problem. Theoretically, this is still a P problem..."
Everyone was listening attentively.
This is a novel content for them. Even if they have an understanding of complexity theory, they have never heard of such in-depth logical issues.
Wang Hao explained for about thirty minutes. When he talked about the problem of reversal of cause and effect, he suddenly caught a glimpse of inspiration.
[Task three, inspiration value 19.]
Got it!
He couldn't control the joy on his face. He immediately put down what he was holding, walked out of the conference room and rushed to the office.
"??"
The students in the conference room were a little confused, but some people still knew what Wang Hao must have thought of.
Luo Dayong hurriedly followed.
"I see!"
Wang Hao sat at his desk and started taking notes, "The key to the problem is to grasp the most important calculations, rather than to conduct all analyses."
"These parameters are complex and each one is included, but there are also important and unimportant parameters."
"You can classify parameters, set sets, and analyze each set."
"This way the logic will be clear."
In one sentence, I made it clear.
Luo Dayong thought hard and knew how to solve the problem.
He focuses on the N-to-1 P problem of complexity theory, while Wang Hao focuses on the study of N-to-1 random three-dimensional function transformation trajectories using combing computational logic.
Because there is basic support from the research on one-to-one three-dimensional function transformation trajectories, as long as the calculation logic is sorted out, the calculation method of N-to-1 random three-dimensional function transformation trajectories can be improved.
After getting the last bit of inspiration and sorting out the complex calculation logic, the research idea was already very clear.
Wang Hao began to make a research summary.
Luo Dayong also made a summary. He summarized the solution given for the N to one P problem.
This theoretical research is enough to support the writing of a top-ranking paper.
For this research on complexity theory, their assignment is still one author and one corresponding author.
All research papers on complexity theory were left to Luo Dayong to write.
Luo Dayong was also a little excited.
In the research direction of complexity theory, it is very difficult to produce results, but now there are new results.
Even the results produced together with Wang Hao are remarkable.
Even if Wang Hao is the one who has made the greatest contribution, for such a major research, the partners of collaborative research are also very important. Academically speaking, most research is not done by one person.
The theoretical results of the first issue completed by the two of them alone are quite remarkable.
For Wang Hao, it was just an ordinary result.
He is more concerned about the research on "random three-dimensional function curve correction" because he knows how valuable similar research applications are.
Taking the missile as an example, the missile can undergo random route changes during its flight, and then it can be adjusted through calculation and slowly corrected to the original route.
This kind of correction can not only be done once, but can theoretically be corrected countless times as long as there is basic support.
If the technology can be developed and mature, as long as the missile is launched, it can automatically "avoid obstacles". From launch to hitting the target, no matter how many interceptions are encountered along the way, it can automatically change its trajectory to avoid it. At the same time, the route will also change.
It's 'very weird' and cannot be calculated conventionally.
What's more, maybe the launching party doesn't know the specific trajectory.
In the end, everything will be corrected to the original route.
Facing such missiles, any air defense system will be meaningless.
