Abstract: A new multi missile synergistic penetration guidance law for cooperative engagement of multiple missiles is proposed to achieve effective penetration based on the induced collision strategy. Firstly, the nonlinear model of multi missile cooperative countermeasures is constructed, and linearized based on the zero effort miss distance and zero effort collision angle. Then, considering that the interceptors and attackers are both second order pilot dynamics, the collision distance and collision angle of each interceptor are extended to the equations of state. And then, the state transition matrix is used to reduce the dimension of the state equations. The collision time matching strategy is used to derive the general form of the multi missile optimal synergistic guidance law, and the penetration guidance law in a typical 2V2 scenario is derived. Finally, the effectiveness of the optimal synergistic lured penetration guidance law is verified by simulation of typical scenarios.
