Abstract In order to achieve effective defense against high supersonic targets such as near space flight vehicles, the midcourse guidance together with terminal phase guidance is used to intercept the targets. First, the design of midcourse guidance is described as an optimization problem with terminal constraints. The problem is discretized and converted into a form of nonlinear programming (NLP) using the Gauss pseudo-spectral method (GPM). The NLP problem is solved online and the optimal guidance law is implemented in a closed-loop in a receding horizon architecture. The algorithm ensures the applicability under the condition of guidance information missing for a short time. Then, the terminal guidance law with target maneuver compensation is designed to reduce the requirement of overload on the interceptor, and the terminal guidance law is implemented based on guidance information estimation. Finally, the stability of the closed-loop guidance system is analyzed theoretically, and the effectiveness of the proposed interception strategy is verified by numerical simulation of the interception against a typical high supersonic target.
