Abstract:

The simulation modeling method of radar signal processing was studied.,and the radar system simulation model was built with the special radar model library dedicated to the System Vue simulation platform. The radar signal processing process in clutter environment is modeled and simulated.Firstly, the process of radar echo generation and the basic principle of radar signal processing are analyzed.Secondly, the functions and parameter settings of target model, clutter/noise model, pulse compression model, MTD model and CFAR model in radar simulation model library are studied.Finally, the simulation model of radar system in clutter environment is built by using SystemVue simulation platform, and the radar signal processing process is simulated based on the data of matrix type.Through simulation, the signal processing results of the radar system model are consistent with the theory, which verifies the correctness of the simulation model.
