Abstract: Autonomous maneuver decision is a key technology in air-to-air confrontation, and the study of autonomous maneu-ver decision involves an optimal maneuver solution method. Through the study of autonomous maneuver decision method, the real-time and accuracy of autonomous maneuver decision of Unmanned Combat Aerial Vehicle (UCAV) in an aerial combat engagement can be improved, which has important theoretical research significance and application value in the promotion of UCAV's autonomous aerial combat and manned/unmanned aircraft cooperative aerial com-bat. Currently, a large number of researches have been conducted around the theories of mathematical solution, data-driven, intelligent optimization and their applications, which have given a greater impetus to the research of autono-mous maneuver decision methods and their applications. Firstly, the basic concept of autonomous maneuver decision of UCAV is elaborated, then the research progress of maneuver decision methods is reviewed, several methods commonly used in maneuver decision research are introduced, the maneuver decision methods are classified and summarized and the performance of several typical maneuver decision methods in air combat simulation is compared. Finally, the difficulties and prospects of autonomous maneuver decision research are pointed out.
