Domestic hypersonic weapon: visible, long whip to the end

Produced ｜ Netease News

Introduction: Today is the 95th anniversary of the founding of the Chinese People's Liberation Army. The war has never gone far. It is just afraid of being strong! The first heart is like a torch, and the journey is like a rainbow. On the road to protecting the security of national defense, people, technology, and heavy weapons are indispensable.

As early as March of this year, Russia's Ministry of Defense spokesman Konacopov announced that Russia used the "dagger" hypersonic missile to destroy an Ukraine -Frankfu large -scale ammunition library in Ivan -Franco in Ukraine. It is believed that this is the first time in human history to use hypersonic weapons in actual combat.

The maximum range of this type of missile reaches 2,000 kilometers. After being separated from the carrier, it will climb with a large elevation corner, and then starts to dive sharply, quickly accelerate to Mach 10, and accumulate sufficient kinetic energy over the target area to complete complex motor movements. At the end of the flight, at the end of the flight Section opens the bomb -up radar to search for the target. Some experts have inferred that the Ukraine's air defense alert has only sounded after the missile hit the target, which shows that the speed and penetration capacity of this type of missile are very good.

Although this reflects that the high -ultrasonic weapon has a good blow to the time sensitive goal, the building is not the real time sensitivity (referring to the strong maneuverability, the firepower projection preparation time is very short, the location is located, the location The type of information that changes quickly with time is to be fast, such as various types of self -propelled artillery, various commands of communication node vehicles, etc., the most typical is the "Hemaas" self -propelled rocket launcher in Ukraine). To truly play the strike efficiency of high -speed weapons on time sensitive goals, it is far from enough to use the hypersonic weapon alone. The speed of intelligence collection and processing greatly affects the strike efficiency. , Positioning, launch, and timely evaluation of strike effects after the target is destroyed.

Does China have this quick processing system that can ensure the efficiency of high ultrasonic weapon strike efficiency? The answer is yes. Due to the high level of confidentiality of this set of systems, it can only be simply evaluated and appropriately associated with some public reports of academic achievements.

1. What is the status quo of the monitoring capabilities of civilian nationality in my country?

In March of this year, my country launched 22 satellites in Wenchang No. 8 Launar Rockets in Wenchang, Hainan, including the "Chaohu No. 1" synthetic aperture radar (SAR) satellite jointly developed by Tianyi Research Institute and North China Water Resources and Hydropower University. Different from ordinary optical remote sensing satellites, it can actively launch radar waves to scan the surface of the earth, and continuously receive the return signal and process it to obtain the target reflex characteristic image. The target of radar waves into a certain angle will form a bunch of regular highlights on the image.

The following pictures can intuitively feel the characteristics of SAR imaging. How can a word abstract, but it is also regular to look at it. After certain training, you can judge the image.

SAR image and optical image comparison

With the development of artificial intelligence technology, the automatic recognition technology of image targets is becoming more and more mature. The use of neural network models to automatically detect some typical targets in areas such as autonomous driving and face recognition. 02 load, deployed the automatic identification software based on the YOLO V5 neural network model (an AI program). It can independently identify the typical ship target. Extracted and output into short newspapers information, and passed to the user end through the short newspaper band of the Beidou 3 system. In other words, as long as you have the Beidou receiving machine, under the blessing of the Beidou navigation system, you can receive the ship information detected in real time anytime, anywhere.

Combined with the real -time processing technology released by Wuhan University before, and comparing the process of automated testing of the "Chaohu No. 1" ship's target automation testing, the imaging method of Chaohu No. 1 is radar imaging, so you do not need to perform optical correction and photography measurement like optical sensors. Method positioning these two steps, so the time required for the entire process is expected to be shorter within two minutes. Compared with optical remote sensing satellites, the synthetic aperture radar satellite also has an unparalleled advantage -radar waves are not affected by light clouds and other environmental, so in military applications, we can cope with the heavenly foundation mission in most complex battlefield environments Essence

Second, the eyes are available, the long whip is here, and there are many more to do

The "Chaohu No. 1" satellite's star -load processor can also upload new neural networks (one of AI programs) such as the ground measurement and control station to automatically detect methods. Uploading the new algorithm through the ground station can be uninstalled by the old algorithm. This technology Lujia No. 3 is already in use. For details, please refer to the "New Generation Smart Surveying and Mapping Remote Sensing Sensing Experimental Satellite No. 3 01 Star". Therefore The ability to diversify observation tasks. Regarding the detection task of aircraft targets, Professor Zhao Lingjun of the University of Defense Technology proposed a series of fast detection methods for the target of SAR image aircraft targets in complex environment. For example, first use AI programs for the airport target testing special training to extract the airport area on the remote sensing image, and then use another AI program to extract the aircraft target. At the same time, the airport target is processed, the airport image is generated. +Airport) integration, this method can avoid the false alarm caused by artificial intelligence interpretation errors, and also improve the detection speed. The process of the target detection of the complex environment SAR image aircraft target detection

Experiments show that it takes 131.2 seconds to use other types of algorithm models, but it only takes 53.4 seconds to use the above -mentioned neural network model for airplane targets to complete the 900 square kilometers large scene SAR image, which has improved.

However, when the airport detection model and fusion steps are added, only 7.3 seconds to complete the target detection and extraction for the same 900 square kilometers.

In addition, the data processing module of the "Chaohu No. 1" satellite uses the YOLO V5 neural network architecture for the AI ​​program of the ship target. It is similar to the architecture of the AI ​​program above. Waiting for SAR satellites with similar functions, to guide high -speed weapons to crack down on simple airports in the first and second island chains, disintegrate the tactics such as "agile combat deployment" and "fast raptors".

After the SAR satellite reaches the island reef, it only takes two minutes to detect the aircraft and airport targets in the area, and automatically generate information such as the type and location of the aircraft and pass it to the command node and the missile launch unit. At this time The missile input fire control parameters and fired in an instant. In this way, the high ultrasonic missile can complete the blow in about 10 minutes, and it takes at least 21 minutes to prepare a aircraft in the U.S. combat planning. It takes at least 1.5 hours to complete the homework. In other words, when the enemy plane landed, our missiles had "reached".

3. Continuous breakthrough and steady upgrade.

Of course, it is obviously not enough to complete the above links, and it is necessary to perform damage assessment. We can also complete this task through satellite networking. According to the public data of the high -scoring satellite No. 3 satellite, the high score 3 constellation consists of three low -orbital synthetic aperture radar satellites. It can be repeatedly observed at any place around the world in four hours. Essence

During the day exercise stage of "Emergency Mission -20122 Joint Society Disaster Rescue Exercise", a total of 5 satellites were mixed with 5 satellites to conduct 6 observations for the exercise area. By the end of the exercise on May 12, a total of 8 satellites were used to observe 17 times for the drill area, and a satellite was over to the top of about 2 hours. After completing the "reconnaissance -strike" process, satellites will soon be used to imagine and evaluate the strike area again. The number of satellites enabled at that time is far more than the current eight high -scoring special satellites.

We can also use the DF-17 to launch DF-15A/16, and use the radar/optical load on the target area to evaluate the effect of the target area. Determine the attack area according to the evaluation results. This can completely paralyze the entire agile combat group. In addition, technologies such as dual -base SAR and satellite formation have been used.

Recently, a missile shooting range satellite picture in my country

Obviously, it may be that the ability to test the missile dual -base SAR and the ability to screen for false targets. The false target next to the main target has different angles. The angle is different. The difficulty of target recognition and judgment, it turns out that we have the ability to hit.

Zero -heavy Space Company Lingzhu Constellation is planned to be mixed with more than 160 satellite mixed groups. According to the plan, the first phase will be completed next year, with a total of 48 satellite networking, which is expected to achieve the frequency of shooting once every hour. After the constellation deployment is completed in the future, it will form a global high -time resolution to observe the ground, which can be "shoot" once in 10 minutes.

Conclusion: The modern information war competition is the ability and speed of various combat units in the system to form the "reconnaissance -strike" cycle. Reconnament and blows will become more and more diverse, and data processing speed and firepower will become faster and faster. I believe our system will lead the world military reform.
