这是一个横虚惊概率的程序，也叫CFAAR，可以实现雷达图像数据的恒虚警检测 -This is a horizontal program of the false alarm probability, also known as CFAAR CFAR detection of the radar image data

基于高斯分布的CFAR检测算法(双参数CFAR检测)，输入一个确定的虚警概率，在满足一定虚警率的情况下对图像进行分割，实现目标与背景的分离。(The CFAR detection algorithm based on Gauss distribution (two-parameter CFAR detection) inputs a certain false alarm probability, and segmentes the image to achieve the separation
