中文说明： 旋转机械二维全息谱计算的实用例程，计算互信息非常有用的一组程序,采用偏最小二乘法，随机调制信号下的模拟ppm，抑制载波型差分相位调制，FMCW调频连续波雷达的测距测角。
English Description：
It is a practical routine for two-dimensional holographic spectrum calculation of rotating machinery. It is a very useful set of programs for mutual information calculation. Partial least squares method is used to simulate ppm under random modulation signal, suppress carrier type differential phase modulation, and range and angle measurement of FMCW frequency modulated continuous wave radar.
