“…These defensive weapons seriously intimidate the survivability of the conventional antiship missiles. Hence, advanced missile guidance technique is becoming important issue such as the impact angle control guidance (IACG) and cooperative guidance, which aims at, in a specific case, making multiple missiles arrive at a single target simultaneously to saturate the target's defence [1][2][3][4][5].…”

The problem of the distributed cooperative guidance law of multiple missiles attacking a stationary target with impact angle constraint is investigated. A distributed cooperative guidance law, which consists of a nonsingular terminal sliding mode component for ensuring finite time convergence to the desired LOS angle and a coordination component for realizing finite time consensus of time-to-go estimates, is proposed. Analysis shows that the guidance law designed in this study can ensure that missiles’ time-to-go estimates represent real times to go once all the missiles fly along the desired LOS. Therefore, simultaneous arrival can be guaranteed. Furthermore, it is modified to accommodate the communication failure cases. Compared with existing results, this guidance law owns faster convergence rate and can satisfy large impact angles. Numerical simulations are performed to demonstrate the effectiveness of the proposed guidance law.
