Multiaircraft gaming confrontation methods with different roles

In this section, a differential countermeasure guidance law for target active defence is proposed for the "three-body" game confrontation situation, in which the target can release a defence missile to assist itself in breaking through the defence when it is manoeuvring to avoid the interceptor missile. Firstly, based on the zero-lag dynamics model, the relative motion model of the target, interceptor missile and target is established. Then, based on the linear-quadratic differential countermeasure theory, the optimal control strategy of each vehicle is designed. Finally, the confrontation scenarios under different cooperation situations between the target and the defence missile are compared and analyzed in the simulation. The results show that when the target acts as a lure to cooperate with the defence missile with a small manoeuvre in the attack on the interceptor, the survival ability of the target can be effectively improved. The results show that when the target acts as a lure and attacks the interceptor with a smaller manoeuvre in cooperation with the defence bomb, the target's survivability can be effectively improved.
