Abstract: In order that multiple missiles can hit a stationary target simultaneously in the desired relative direction of the missile-target Line-of-Sight(LOS) in the plane, a time-cooperative guidance law for multiple missiles with spatial cooperation is proposed. Based on in-plane missile-target relative motion equations, a time cooperative guidance model for multiple missiles with spatial cooperation is constructed. Based on the theory of multi-agent cooperative control, in LOS direction, a distributed time-cooperative guidance law is postulated, which can guarantee that all missiles' impact times reach consensus in a finite time. In the vertical direction of LOS, a distributed space-cooperative guidance law is postulated, which can guarantee that missiles' relative LOS angles converge to the desired values in a finite time. Numerical simulations demonstrate that the proposed cooperative guidance laws can ensure that multiple missiles hit the target simultaneously in the desired relative directions of the missile-target LOS.

Key words: spatial cooperation, time cooperation, multi-agent cooperative control, relative line-of-sight angle, finite time
