英文摘要： The background of this project is the terminal guidance strategy and guidance law design problem under a complex engagement battlefield, in which the target may perform unknown maneuvers and release decoys or false objects flying around to avoid being intercepted. The finite-time dynamic game and its application in the the terminal guidance design in the situation under consideration will be studied in this project. First, we will analyze the engagement course between an intercepting missile and a maneuvering target around with decoys or false targets, and establish a finite-time dynamic game model to describe the problem. Then, the global equilibrium strategy of the proposed finite-time dynamic game will be given, and the characteristics of the equilibriums will be analyzed, a strategy fast solving algorithm will be proposed based on receding horizon optimization in a logical matrix strategy space. Thirdly, a terminal guidance approach, including guidance strategy and guidance law, will be addressed based on the proposed finite-time dynamic game method, in which the target level of interest and power center concept are introduced. The guidance strategy and guidance law are designed for terminal guidance system under a complex engagement and detective enviroment. Last, the numertical simulations will be done to show the effectiveness of the proposed approach. The aim of the project is to provide a sound theoritical foundation for the design of guidance strategy and guidance law. The research of this project will also be helpful for the game problem research such as the spacecraft or ballistic missle penetration.
