说明：  雷达恒虚警检测（CFAR）一维距离像蒙特卡洛仿真，探究不同信噪比下CFAR检测概率，在一维CFAR基础上修改程序得到。参考《雷达信号处理基础》一书。
(One dimensional range profile Monte Carlo simulation of CFAR is used to explore the probability of CFAR detection under different signal-to-noise ratio. The program is modified based on one-dimensional CFAR. Refer to the book "Fundamentals of radar signal processing".)
