Efficient information-based cooperative guidance law of multi-missiles

Abstract

This paper investigates a novel cooperative guidance law for the task of salvo attack based on efficient information. The concept of efficient information is first introduced as the basis of a multi-missile cooperative structure in a nominal engagement situation. The effective time of the efficient information, which can be regarded as an important parameter to indicate the ability of a missile to attack a given stationary target, is estimated by modifying the current time-to-go estimation method in the presence of a lateral acceleration constraint. Utilizing the effective time, a novel cooperative guidance law with better adaptiveness and robustness is proposed for multi-missile systems to realize the simultaneous attack. Finally, the effectiveness of the proposed cooperative guidance law is demonstrated via simulations.
