Modern beyond visual range air combat has the characteristics of high dynamic complexity and multi-factor interweaving, and it is difficult for traditional decision-making methods to clarify the overall air combat process and solve the problem. In this paper, aiming at the autonomous decision-making problem of single-plane beyond visual range air combat, an autonomous decision-making framework is constructed, which takes into account the whole process elements of air combat, and tactical rules with both offensive and defensive functions are designed to form an autonomous air combat decisionmaking method with rule-driven as the main mechanism. The simulation results show that the autonomous decision-making method designed in this paper can effectively improve the maneuvering decision-making ability of fighter aircraft and has good application.
