Time Cooperative Guidance Law for 3D Virtual Perspective of Low Speed Moving Target in Sea Scenario

In this paper, a 3D virtual cooperative time guidance law for moving targets is proposed. Polynomial idea and implicit cooperative idea are introduced, and the motion relationship of virtual relative coordinates system in two-dimensional plane is deduced to three-dimensional, and based on this, the 3D virtual time cooperative guidance law is deduced. The guidance law can ensure the time consistency and overload consistency of multiple missiles. The effectiveness and feasibility of the guidance strategy in various scenarios are verified by mathematical simulation.
