Description
Technical Field
[0001] This invention belongs to the field of guided weapon technology, specifically relating to an image-guided rocket weapon system based on ground-assisted identification. Background Technology
[0002] With the development of microelectronics and guidance and control technologies, and the pursuit of precision strikes and high-efficiency destruction capabilities in combat operations, precision guidance of weapons has become the main direction and trend of weapon development. In recent years, the guidance of field rocket weapons has been the most important and fastest-growing research direction. Field rockets have developed simplified control and satellite-inertial combined guidance systems. Although the simplified control scheme has seen some development due to its low cost, its limited control capabilities prevent precision strikes, and it has gradually been phased out of development. Satellite-inertial combined guidance technology, due to its advantages such as improved satellite positioning accuracy and all-weather operation, has been widely applied to long-range and ultra-long-range guided rocket weapon systems in field applications. However, satellite-inertial combined guidance suffers from drawbacks: after the satellite is jammed, the accuracy of inertial guidance decreases significantly with increasing range; furthermore, the aforementioned guidance methods cannot strike moving targets.

[0102] Example 1
[0103] The image-guided rocket weapon system based on ground-assisted target recognition constructed in this invention mainly consists of the following:
[0104] The system comprises a command vehicle system, an unmanned aerial vehicle (UAV) reconnaissance system, a rocket launcher, image-guided terminal-guided rockets, and a ground-assisted target identification system. The rocket launcher serves as the launch platform for the rockets; one launcher can carry 2 to 40 image-guided terminal-guided rockets, depending on the size of the rockets. The image-guided terminal-guided rockets mainly consist of a seeker head protective shroud, an image seeker head, a flight control device, an inertial navigation device, a satellite positioning device, an onboard wireless image data transmission device, an onboard power supply, servo motors, a solid rocket motor, a warhead, and a fuze. The ground-assisted target identification system mainly consists of a ground image control device, a ground image data transmission device, a data link antenna, and an auxiliary target identification unit. The system composition of this invention is described in [details omitted]. Figure 1 Image of a terminal-guided rocket Figure 2 Ground image control system (see) Figure 3 See system information transmission relationship Figure 4 .
[0105] The workflow of this invention is as follows: Figure 5An example of the workflow is that the command vehicle system sends instructions to the UAV reconnaissance system to conduct target reconnaissance and transmits target images and coordinates back to the command vehicle system. Based on the reconnaissance situation and operational mission requirements, the command vehicle determines the number of rockets to use and whether to use human-in-the-loop attack mode or template matching mode. When using template matching mode, the command vehicle prepares the target template and transmits the target template and coordinates to each rocket launcher via radio or wired connection. Upon receiving the target and operational mission, the rocket launcher powers on its image-guided rockets, completes self-checks, and sets the target template and coordinates. The rockets are then launched. The rockets first undergo mid-course guidance flight using information from satellite positioning and inertial navigation systems. Before reaching the seeker's effective range, the seeker jettisons its nose cone. The seeker then matches the target template with the target. If a match is successful, the seeker tracks the target and outputs the line-of-sight angular velocity to the flight control unit. The flight control unit integrates the information from the inertial navigation system and satellite... The positioning device generates servo control commands, which in turn deflect the control wings to guide the image-guided rocket to the target. The fuze and warhead then engage, achieving precise damage to the target. In man-in-the-loop attack mode, the command vehicle transmits target coordinates and other information to the rocket artillery and ground image control system via radio or wired communication. The rocket artillery calculates the firing angle and trajectory, the image-guided rocket is powered on, information is set, and alignment is transmitted—a series of preparatory tasks. The ground image control system, based on commands from the command vehicle, activates the ground image control device and connects the data link antenna. The system performs tasks such as receiving direction calculation and adjustment, and setting communication frequencies. When the rocket artillery fires a terminally guided rocket, it synchronizes the launch time with the ground image control system. The ground image control system actively sends a synchronization signal. When the onboard image data transmission system receives the synchronization signal from the ground image data transmission system, it sends a response signal to establish communication with the ground image data transmission system. It then wirelessly transmits the flight parameters of the terminally guided rocket and the seeker image to the ground image data transmission system. The ground image transmission system decodes the received information and sends it to the ground image control system and the auxiliary identification device. The ground image control system displays the received flight parameters of the terminally guided rocket on its display screen and overlays the seeker image and the target coordinate information output by the auxiliary identification unit onto the seeker image, displaying them simultaneously on the image control system's display screen. When the terminally guided rocket reaches a certain distance from the target, the flight control system issues a seeker head jettison command. The seeker head jettisons the image, and the seeker compresses the target area image acquired by the rocket and transmits it to the ground image control system via the onboard image data transmission system.The auxiliary identification unit in the ground image control system processes the seeker image, identifies targets within it, and assigns them numbers based on their probability of detection. Targets with higher probabilities are numbered "1," and so on, distinguishing up to five targets. The identification results are then sent to the ground image control device, which displays them in real-time on a screen. The operator confirms the target using function keys or number keys on the keyboard. The ground image control system transmits the target confirmation information to the onboard image data transmission device, which in turn sends it to the seeker. The seeker locks onto the target and automatically tracks it. Simultaneously, the seeker transmits the target tracking line-of-sight angular velocity to the flight control device. The flight control device integrates information from the inertial navigation system and satellite positioning system to generate flight control commands, which are then sent to the servo motors to guide the terminal-guided rocket towards the target, achieving a precise strike.
[0106] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
