<p>Coordinated multi-missile target engagement is a critical technical challenge in modern warfare and aerospace, where cooperative impact angle coordination is an essential component. This paper presents a novel cooperative guidance law for multi-missile impact angle coordination, leveraging prescribed-time consensus theory. The proposed cooperative guidance law builds upon the biased proportional navigation guidance law by incorporating a consensus variable to cooperate impact angles during multi-missile flights for both unified angle and angle range attack. Additionally, the guidance law is extended to moving target engagement in a relative motion coordinate system. Furthermore, the paper presents mathematical modeling and theoretical analysis to substantiate the guidance law’s convergence and boundedness. Validated through numerical simulations, the guidance law proves effective across various initial conditions and combat scenarios, enabling coordinated multi-missile strikes.</p>
