Summary of Key Technologies of Interceptor Guidance and Control in Near Space Defense Operations

In order to meet the needs of near space defense combat, focusing on key technologies of guidance and control for intercepting near space vehicle, this paper reviews the current research progress from the five aspects of “midcourse guidance”, “mid-terminal guidance handover”, “terminal guidance”, “blended control by using reaction-jet and aerodynamics” and “multi-interceptor coordinated interception”, and it looks forward to several directions that may require key development in the future, including “cooperative trajectory generation technology for multiple interceptor based on region segmentation”, “cooperative trajectory correction of multiple interceptors based on distributed optimization” and “research on dynamic capture region of the coordinated terminal guidance law of multi interceptors”.This paper can provide some reference for the research on the guidance and control technology of near space interceptor.
