FMCW雷达多运动目标检测

FMCW雷达多运动目标检测

去年的时候做了一个基于FMCW雷达多运动目标检测的matlab程序，对多运动目标检测，以图像的方式显示结果。效果还可以，能够同时实现高速多目标、大距离范围内的目标检测，程序的链接为（在mathworks网站的File Exchange里面）：

下面是几个结果：


程序在matlab2018b下正常运行，需要Phased Array System Toolbox工具箱。
回波信号产生程序如下：

% This program generate the FMCW signal reflected from targets, mainly
% modified from the example of "phased.RangeEstimator System
% object" in matlab 2018b. It need the "Phased Array System Toolbox" to
% work.
