Cooperative Guidance Law of Multi-Missile Dynamic Roundup Based on Target Dubins Escape Domain

Aiming at large maneuvering target, a cooperative guidance law of multi-missile dynamic encirclement based on Dubins escape domain is proposed in this paper. Firstly, the target Dubins escape domain is constructed according to the target Dubins escape path. By introducing virtual target points, the dynamic trapping strategy is designed, and the cooperative guidance model of multiple missiles and multiple virtual targets is established. Secondly, based on the prescribed-time stability theory, the line of sight and line of sight normal cooperative guidance law of multiple missiles is designed to control the remaining flight time and line of sight angle, and the stability proof of the designed cooperative guidance law is given. Finally, the simulation verifies that the cooperative guidance law in this paper can carry out cooperative attack on large maneuvering targets without presetting the terminal line of sight angle and attack time in advance.
