提出了一种微波传感器信号的处理方法。该方法的应用允许实质上提高多普勒频率和相关联的信息参数的确定的准确度。这里，通过对称锯齿律改变的频率调制与上升和下降部分上的输出信号的频谱处理一起使用。多普勒频率由频谱包络的互相关函数计算，这使得可以消除由多普勒信号的频谱结构引起的误差。
A method of processing microwave sensor signals is proposed. Application of this method allows substantially improving the accuracy of determination of Doppler frequency and associated information parameters. Here, frequency modulation changing by the symmetric saw-tooth law is used with spectral processing of the output signal on rising and falling sections. The Doppler frequency is calculated from the cross-correlation function of the spectral envelope, which makes it possible to eliminate error caused by the spectral structure of the Doppler signal.
