Deviated Pursuit based Cooperative Simultaneous Interception against Moving Targets

This work focuses on achieving cooperative simultaneous interception against moving targets using the concepts of deviated pursuit guidance strategy. Unlike most existing salvo guidance strategies which use estimates of time-to-go, based on proportional navigation guidance, the present strategy uses exact expression for time-to-go to ensure simultaneous interception. The guidance command is derived considering nonlinear engagement kinematics. Weighted consensus in time-to-go over a pseudo-undirected graph is used to intercept a moving target cooperatively. It has been shown that through a judicious choice of these weights, the achievable set of interception times expands. Simulations are provided to vindicate the effectiveness of the proposed strategy.
