In order to provide an all-round, all-factor and all-process combat training environment, a radar simulation training scenario generation system is designed. This paper analyses the characteristics and characteristics of radar equipment facing complex battlefield environment, constructs a radar detection environment close to actual combat according to certain construction principles, designs and realizes the functional structure, system flow and key technologies of radar simulation training according to the scenario data and the scenario generation process, and proves the application of different modes in training. The application results show that the system works well in radar simulation training.
