Cooperative Multi-Missile Guidance Research Considering Communication Topology Switching

Abstract

A time-space cooperative guidance law based on switching strategy is proposed for the multi-missile cooperative strike problem under switching topology. The distributed guidance law is designed for the time constraint in combination with the consistency algorithm, and it is proved that the system converges in finite time based on Lyapunov theory and can achieve simultaneous strikes. For spatial constraints, the ballistic shaping guidance law is used to make each missile converge to the desired line of sight angle. The switching strategy is designed so that missiles can achieve both temporal and angular coordinated attacks. The simulation analysis verifies that the designed guidance law can achieve the flanking attack and angular constraint under the switching topology condition and the loss of one missile from the group.
