According to the main function structure of fire control radar simulation, the multi-search and tracking simulation models of radar are established, and the general target search and tracking algorithm of fire control radar for simulation training is designed. Based on the plug-in form, the system interaction mode is realized by using the base class object pointer and the inheritance class object as the parameter, and the data model and logic model of radar interaction are established by using the abstract factory pattern architecture, and the test analysis is carried out through the radar visual test environment. The experimental results show that the method realizes the air-to-air mode simulation model of simulation training general fire control radar, and realizes the reusability and reconstruction of the model.
