GO-CFAR检测是信号处理中非常常用的检测方法。该程序比较了理论值和实际值的仿真结果。实际中雷达信号往往是起伏的，该程序从SweringI型为例。(GO-CFAR detection is very commonly used detection methods in signal processing. The program compares the simulation results of the theoretical and actual values. The actual radar signals often are ups and downs of the program from SweringI type, for example.)
