中文说明：程序描述了恒虚警的均值类算法，详细了描述他们在不同环境下的虚警概率和信噪比的曲线（均匀杂波背景，存在杂波边缘的杂波背景，多干扰目标的杂波背景）。从此给其他新提出来的算法他提供理论分析的依据。程序大部分是从理论公式推导，所以结果较准确。
English Description：
The program describes the mean algorithm of CFAR, and describes in detail the curve of CFAR probability and SNR in different environments (uniform clutter background, clutter background with clutter edge, clutter background with multiple interference targets). From then on, it provides theoretical basis for other new algorithms. Most of the programs are derived from theoretical formulas, so the results are more accurate.
