Distributed guidance law design for cooperative simultaneous attacks with multiple missiles

Researchers reconsider the distributed guidance law design problem for cooperative simultaneous attacks against a stationary target with multiple missiles. A general idea is put forward to deal with the difficulty in achieving the consensus of missile’s real times to go, or to design a guidance law that can assure that all missiles will hit the target, make all missiles’ time-to-go estimates reach agreement, and ensure that missiles’ time-to-go estimates represent real times to go once the consensus error of the time-to-go estimates converges to zero. Two distributed guidance laws are proposed based on two commonly used time-to-go estimates as examples of the realization of the aforementioned idea.
