There are many problems faced by cognitive Electronic Warfare (EW) equipment, including complex and diverse combat scenes, being difficult to obtain real data and high cost of actual combat training. In order to meet the needs of scheme demonstration and key technology research, by combining artificial intelligence with system simulation technology, the signal level model of cognitive EW equipment and its typical combat objects is established. The information interaction process between EW equipment and combat objects in complex electromagnetic environment is simulated. A learning training and simulation evaluation system for future battlefield cognitive confrontation is built. The function, architecture, workflow and key modules/models of the system are introduced in detail. The application examples of the system are analyzed. According to the application effect, the system can provide guidance for intelligent algorithm model training of cognitive EW and the simulation test evaluation on equipment combat capability.
