Z-N整定 PID整定 SIMULINK模型，参照书上的Z-N整定模型搭建(Z-N tuning PID tuning SIMULINK model, reference book Z-N tuning model)

说明：  EMD的子程序，刚刚忘记了不好意思，真的不是为了刷程序数量(EMD of the subroutine, just forget I am sorry, do not amount to brush program)

基于知识的恒虚警检测——KB-CFAR检测器：包括对于无目标、仅有噪声的信号进行KB-CFAR检测的仿真，以及对于含目标、且在瑞利杂波背景下的KB算法仿真。一些程序主要是为了绘图，画出KB-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KB-CFAR检测过程中的检测概率和虚警概率。(KB-CFAR detectors: simulations of detection to signals with no target but noise only, as well as signals with target and the background of Rayleigh clutter. Some programs are aimed at giving pictures of the signals and detectiong threshold in the process of detection using KB-CFAR algorithm, while other programs are aimed at calculating the detecting rate and false alarm rate of KB-CFAR algorithm.)
