The calculation bottleneck of radar electronic signal level simulation system is analyzed,and a design idea of parallel simulation system based on front-end and back-end architecture is proposed.Through the physical separation of front-end simulation display control and back-end simulation operation,the resource contention between model display control and model operation and the time-consuming problem of human-machine interface display are solved.The centralized simulation operation in the background can not only solve the time-consuming problem of network data communication transmission through the data interaction mode of shared memory,but also make full use of the advantages of high-performance computing resources to solve the time-consuming problem of signal level equipment model operation through parallel computing technology.In view of the two key technical problems in the construction of simulation system,the specific solutions are given.On this basis,the simulation prototype system is constructed,and the simulation speed is tested for different hardware resources.The test results show that the parallel simulation system architecture has greatly improved the simulation efficiency.
