Cooperative guidance law design for simultaneous attack with multiple missiles under directed communication topologies

This paper concerns the guidance law design problem of multiple missiles simultaneously attacking a non-maneuvering target under a directed communication topology. With using the relative range between the missile and the target over their closing speed as the time-to-go estimate of the missile, a cooperative guidance law in a fully distributed fashion is designed to synchronize the missiles' time-to-go estimates, and furthermore ensure the consensus of the missiles' real times-togo. The validity of the proposed method is demonstrated both in theoretical analysis and in simulation results.
