Cooperative Guidance Law Design for Salvo Attacks with Impact Angle Constraint

In this paper, a novel cooperative guidance law is proposed to make multiple missiles hit simultaneously the same target at a pre-specified impact angle. Firstly:, the normal acceleration which changes the velocity direction is designed such that all missiles will fly along the desired line of sight (LOS) after a given time which ensures the hit-to-kill interception; then the consensus variable is constructed using available information and can reach consensus under the proposed the tangential acceleration command which determines the velocity magnitude. Hence simultaneous hit-to-kill attack is achieved. Finally, some simulation studies are performed to verify the effectiveness of the proposed scheme.
