摘　　要：为提高设计雷达信号处理系统的效率,在matlab软件平台上结合数字信号处理理论建立了雷达信号处理模型,并在此基础上进行了仿真。系统对线性调频信号、非线性调频信号等常用雷达信号的产生和处理过程进行了计算机仿真,雷达信号处理主要体现为时域和频域的脉冲压缩,包括加权前、后脉冲压缩波形的比较。系统具有显示的直观性、实时性与逼真性,而且具有很强的扩展性,可用于与雷达信号处理有关的教学与科研、试验分析。典型仿真范例及结果表明用matlab仿真雷达信号处理系统是方便和高效的。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.
