Review of research on reentry guidance methods and hot issues of hypersonic gliding vehicle

Hypersonic glide vehicle is a kind of near-space vehicle with important strategic value, and its reentry guidance is one of the key issues of current research. Firstly, the development history of the reentry guidance method of hypersonic gliding vehicle is combed, and the principle and research status of the nominal trajectory guidance method, predictive correction guidance method and closed-loop optimal guidance method are summarized, and their characteristics and limitations are analyzed. Secondly, the current hot research issues and related key technologies in the field of reentry guidance are analyzed and elaborated, such as reentry coordinated guidance, reentry robust trajectory optimization, reentry change system guidance, and reentry intelligent guidance. Finally, the current research on the reentry guidance method is summarized, and its future development direction is briefly prospected.
