Problems solved by technology
The micro-classification method takes the field in space as the unknown quantity when analyzing the target, and needs to discretize a certain space (including the air) surrounding the target. Therefore, for clustered UAV formations, this type of method has a large amount of calculation; This type of method only needs to discretize the target surface or internal volume area, which is suitable for the analysis of cluster targets, but its computational complexity is high, and ordinary computers cannot bear it.
It can be seen that the existing technical solutions not only cannot realize dynamic calculation, but also have a large amount of calculation

Embodiment Construction
[0052] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection of the present invention. scope.
[0053] As mentioned earlier, the current electromagnetic modeling and simulation technology for UAVs is still based on static and traditional numerical methods. In the static calculation process, the dynamic scene of the UAV cluster is segmented frame by frame. Each frame is calculated separately, and the calculation processes of each frame are not rela...

The invention provides a dynamic group target electromagnetic scattering characteristic calculation method and device. The method comprises the following steps: acquiring scene information of a to-be-analyzed group target; generating constant data according to the scene information of the to-be-analyzed cluster target; obtaining each frame of scene of the to-be-analyzed cluster target in real time, and executing the following steps for each frame of scene: calculating variable data corresponding to the frame of scene, and calculating and generating electromagnetic scattering characteristics corresponding to the frame of scene by using the variable data corresponding to the frame of scene and the constant data. According to the scheme, when each frame is calculated, calculation of constant data is omitted, and the calculation amount of the dynamic electromagnetic scattering characteristics is greatly reduced.
Description
technical field [0001] Embodiments of the present invention relate to the field of electromagnetic technology, and in particular to a method and device for calculating dynamic electromagnetic scattering characteristics of cluster targets. Background technique [0002] UAV cluster is an intelligent cooperative combat cluster composed of a large number of drones. Its platform is miniaturized, its penetration capability is strong, its flying conditions are low, its body is cheap, and its cost-effectiveness is high. It will become one of the main forms of combat in the future. UAV swarms mainly perform combat tasks such as battlefield intelligence reconnaissance and surveillance, saturation attack, electromagnetic interference and suppression, and electronic decoys, which pose a huge threat to future air defense operations, and it is urgent to conduct research on anti-UAV swarm operations. The first link in anti-drone swarms is to be able to detect drone swarms. The individuals...
