Research on Optimal Terminal Guidance Law for Surpersonic Anti-Ship Missile

The problem of terminal guidance of a surpersonic anti-ship missile is studied in this paper. Using the concept of pseudo control variable, a simple state equation is constructed which describes the relative motion between an anti-ship missile and a target ship. The optimal terminal guidance law is deduced for the anti-ship missile according to the optimal control theory. It guarantees the minimum of miss amount and energy consuming. Finally, a simulation example is illustrated to research, and the results show the validity of the designed optimal terminal guidance law.
