Distributed Guidance Law Design for Cooperative Simultaneous Attacks with Multiple Missiles

摘要

This Note studies the distributed guidance law design for cooperative simultaneous attacks against a stationary target with multiple missiles. First, a general idea is put forward to deal with the difficulty in achieving a consensus of the missiles' real times to go. Then, two distributed guidance laws based on different time-to-go estimates are presented, which can achieve a finite-time consensus of the missiles' real times to go, and thus can solve the simultaneous attack problem well. Furthermore, the results are extended to the communication failure case where one of the missiles cannot get information from others. The guidance laws designed in this Note only require the onboard time-to-go estimates of each missile and its neighbors, and thereby are fully distributed, significantly improving the operational effectiveness and reducing the communication burden. Compared with previous related works where the missile acceleration command was assumed to be perpendicular to its velocity, the guidance laws designed in this Note introduce the tangential acceleration, and thus greatly improve the efficiency of the control inputs.
