Simultaneous attack of a stationary target using multiple missiles: a consensus-based approach

Abstract

This paper considers the simultaneous attack problem of multiple missiles against a stationary target.Built upon the classic proportional navigation structure, we propose a consensus-based approach to design the cooperative guidance law.Specifically, we present time-varying navigation ratios for the missiles, which exchange the time-to-go estimates between neighboring missilesvia a communication network. For the cases where the communication topology is undirected or in the leader–follower structure with a missile acting as the leader whose navigation ratio cannot be tuned, we show that the proposed cooperative guidance law can solve the simultaneous attack problem. The effectiveness of the theoretical results is finally illustrated by numerical simulations.
