Radar Signal Processing Simulation System Based on MATLAB

This paper gives a model of radar signal processing based on digital signal processing theory and matlab software platform to improve efficiency of designing radar signal processing system. A simulation based on this model is also presented. The system simulates the production and processing of radar signal, such as linear frequency modulation(LFM) signal and Non-linear frequency modulation(NLFM) signal. Radar signal processing represents mainly pulse compression of time-domain and frequency-domain, including comparison of fore-and-aft pulse compression waveform. The system has not only visual display, real-time character and reality, but also strong expansibility, can be used in teaching and scientific research and experimentation analysis related to radar signal processing. Several typical simulation examples and results show that it is convenient and effective using Matlab to simulate radar signal processing system.
