Distributed cooperative guidance of multiple anti-ship missiles with arbitrary impact angle constraint

The problem of distributed cooperative guidance with arbitrary impact angle constraint is addressed. A new distributed cooperative guidance law, which consists of a local control term to achieve zero miss distance and the desired impact angle, and a cooperative control term to achieve the consensus of impact time, is proposed. A sufficient condition in terms of the properties of the arbitrary time-varying sensing/communication topologies is established to achieve the consensus of impact time. Furthermore, the sufficient condition is extended to the case of the specific topology of leader-followers. Compared with the existing results, the proposed sufficient condition is less restrictive, making the proposed guidance law be capable of real implementation. Numerical simulations are presented to illustrate the effectiveness of the proposed guidance law.
