从飞行器无导引头的主-从式多飞行器协同制导方法

A three-dimensional cooperative guidance method is presented to investigate the problem of leader and seeker-less follower flight vehicles attacking on the targets by sector coverage. An impact time control guidance law with fixed-time convergence is presented for the leader to reach a target at desired impact time. A sector coverage configuration against target with dynamic self-adjusting center and radius is proposed with the leader as baseline. Finally, on the basis of the desired converge sector, the cooperative guidance law is given for the followers to reach the target simultaneously with multi-directional sector blockade. A theoretical analysis is given to prove the stability of the proposed method. The simulated results show that the proposed method can be used to make all the flight vehicles hit the target at appointed impact time, and the leader and the seeker-less followers can form the coverage situation towards the target.
