摘 要现代雷达系统日益变的复杂，难以简单直观的进行分析，必须借助计算机来完成对系统的各项功能和性能的仿真。针对现代雷达信号处理的主要方式,运用数字信号处理理论和Matlab 软件讨论雷达信号处理的仿真问题,提出了一个仿真模型。该模型可以完成雷达信号的仿真、热噪声与杂波的产生和雷达系统中信号的动态处理过程.用Matlab 对某脉冲压缩雷达信号处理系统进行了仿真，得到了雷达系统中各个处理点上的具体信号形式，既包含幅度信息,又包含相位信息，该模型能较好地满足对雷达信号处理的仿真要求，显示了用Matlab仿真雷达信号处理系统的方便、快捷的优雷达点。本文讨论的是雷达信号处理部分，并结合雷达处理系统实例来说明MATLAB在雷达信号处理机系统仿真中的应用。关键词：雷达信号处理;正交解调；脉冲压缩；回波积累；恒虚警处理AbstractModern radar systems become increasingly complex and difficult to simple intuitive analysis, we must rely on computer systems to complete the functionality and performance of the simulationThe simulation of radar signal processing is an important part of the simulation of radar system。 This paper introduces a method of the simulation of radar signal processing based on Matlab， including the simulation ofradar echo and clutter, and researches the simulation method of important technologies in the radar signal processing， including quadrature sampling， pulse compression， echo accumulation and CFAR detector.
