Aiming at the defense strategy for high speed targets in near-space based on the air-breathing hypersonic platform (ABHP), an online proportional guidance midcourse guidance method for near space targets is presented based on an air-breathing hypersonic platform. According to the airframe/scramjet integration coupling characteristics of aspirated hypersonic interception platform, the special working conditions of scramjet, and the flight characteristics of air-breathing hypersonic platform, an online trajectory generation method is provided to enhance the performance of the scramjet engine. In this method, the midcourse guidance law design is based on the transition condition of midcourse and terminal guidance. The proportional coefficient and throttle are taken as the optimization variables, and fuel consumption is taken as the performance index. The optimal control method is used to solve the guidance law design problem under multiple constraints and the comparison simulation results illustrate the effectiveness as well as the advantage of the proposed scheme.
