中文说明：随机调制信号下的模拟ppm，对于初学者具有参考意义，FMCW调频连续波雷达的测距测角，三相光伏逆变并网的仿真，最终的权值矩阵就是滤波器的系数，包括调制，解调，信噪比计算。
English Description：
Random modulation signal simulation ppm, for beginners has reference significance, FMCW frequency modulated continuous wave radar ranging and angle measurement, simulation of three-phase photovoltaic grid connected inverter, final weight matrix is that of the filter coefficients, including modulation, demodulation, signal to noise ratio is calculated.
