New Impact-Time-Control Guidance Law for Maneuvering Targets with Field-of-View Constraint

In this paper, a novel guidance law aimed at intercepting targets of various motion forms with impact time and additional field-of-view (FOV) constraints is investigated. The polynomial function in range domain is designed to derive the guidance command in new-defined virtual relative frame, and the function of seeker's virtual FOV is introduced in the form of additional feedback term to achieve simultaneous constraints on impact time and FOV. Compared with existing methods based on numerical routines with open-loop formulations, the proposed guidance method has the potential to gain better performance in practical applications due to its analytical solution. The availability and practicability of the guidance method are demonstrated by simulations in various combat scenarios.
