内包含频域滤波的步骤及MATLAB代码，是频域增强中所必须知道的哦，还有一个用巴特沃思滤波器效果的例子。(Contains the frequency domain filtering steps and MATLAB code, is enhanced in the frequency domain needs to know Oh, and a Butterworth filter with the effect of example.)

能读取具有位置和机动信息的雷达数据,并将其按地址存储！(read and store the radar data!)

说明：  里面包含多种综合评价方法，如层次分析法、模糊综合评判、基于可拓学的综合评价方法、数据包络分析法、TOPSIS分析法、熵权法以及人工神经网络分析法(It contains many comprehensive evaluation methods, such as analytic hierarchy process, fuzzy comprehensive evaluation, extension-based comprehensive evaluation method, data envelopment analysis method, TOPSIS analysis method, entropy weight method and artificial neural network analysis method.)

this is a code that performs Hilbert Huang tranform

通过产生两个高斯分布的随机数，组合生成瑞利分布的信号，模拟瑞利信道，然后将一个正弦信号以不同方式通过，比较是否有变化。(By generating two Gaussian distributed random number, combined Rayleigh distribution of signal generation, analog Rayleigh Road, then a sinusoidal signal in different ways by, more if there are changes.)
