Aiming at the initial design of vector missile miss distance measurement system, it is not easy to carry out field and physical tests. In order to deeply analyze the performance of the system, SystemVue software is used for modeling, and an efficient and intuitive simulation system for frequency modulation continuous wave (FMCW) missile vector miss distance measurement is established. The system conducts theoretical and simulation analysis of signal generation, MIMO transceiver antenna, echo signal generation, mixing, digital-to-analog conversion, FFT, CA-CFAR modules, and focuses on the systems key parameters such as digital-to-analog converter sampling rate. The results of debugging comparison are shown. The results show that the simulation system established in SystemVue can realize efficient and dynamic missile vector miss measurement. The parameter debugging is simple and the results are intuitive. It has great significance for the design improvement of missile vector miss measurement.
