Guidance law in distributed cooperative air-to-air missile considering detection effectiveness
With multiple air-to-air missiles intercepting high-speed moving targets against the trajectory as a back-ground,a distributed cooperative mid-guidance law with coordinated detection as the terminal constraint is proposed.By analyzing the error source and the error transmission link,a calculation model of the mid-end handover probability is estab-lished,and the collaborative visual field splicing method is studied based on the virtual guide point.In the normal direction of the line of sight,an optimal guidance law based on Gaussian pseudospectral method is designed for the constraint con-ditions such as position coordination and angle coordination.In the line of sight,based on the second-order multi-agent consistency theory,a distributed time cooperative guidance law is designed,and the Lyapunov functional is constructed to prove that the method can stabilize the system in a finite time,and the upper bound of the consistency time is derived.The simulation results show that the guidance law can enable multiple missiles to reach the designated handover area at the same time with their respective expected line-of-sight angles,realizing the needs of field of view splicing and cooperative detection and effectively improving the probability of middle-end handover.
