Study on Pilot's Assistant system based on expert system for BVRAC (Beyond Visual Range Air Combat)

Beyond Visual Range Air Combat (BVRAC) was the crucial stage in the modern air combat. An intelligent Pilot's Assistant (IPA) System for BVRAC was developed based on expert system (ES). The functions and structure of IPA were presented. The knowledge represent, mechanism of the inference engine, and knowledge base of expert system based on CLIPS were investigated emphatically. The input of the expert system included information data of both sides in air combat and data of missiles that have been launched. The output included the methods of maneuver, missile launch, and jamming. Rules of ES were organized into two levels, Field-Judging and Counterwork-Method-Choosing. A distributed real-time simulation system was developed and the simulation results demonstrate the effectiveness of aiding system and the feasibility of tactics-level assistant of IPA.
