中文说明：
有序统计量恒虚警检测——OS-CFAR检测器：包括对于无目标、仅有噪声的信号进行OS-CFAR检测的仿真，以及对于含目标、且在瑞利杂波背景下的OS算法仿真。一些程序主要是为了绘图，画出OS-CFAR检测过程中的信号波形以及检测门限对比图；而另一些程序是为了计算OS-CFAR检测过程中的检测概率和虚警概率。
English Description：
Ordered statistics CFAR detection - os-cfar detector: including the simulation of os-cfar detection for the signal with no target and only noise, and the simulation of OS algorithm for the signal with target and in the background of Rayleigh clutter. Some programs are mainly for drawing, drawing the signal waveform and detection threshold contrast diagram in the process of os-cfar detection; Other programs are designed to calculate the detection probability and false alarm probability of os-cfar
