Micro-motion detection data processing method, system and device and medium

The invention discloses a micro-motion detection data processing method, system and device and a medium, and the method comprises the steps: carrying out the preprocessing of an original signal, carrying out the segmentation of a collected micro-motion signal according to a proper time window, calculating a spatial autocorrelation coefficient and a standard deviation, fitting a frequency dispersion curve, carrying out the weighting processing, and finally obtaining an extracted frequency dispersion curve through solving a target function. And meanwhile, the apparent shear wave velocity can be calculated for inverting underground structure characteristics. The method has the advantages that the influence of measurement disturbance on frequency dispersion curve inversion is eliminated, and the inversion precision is improved. And the resolution capability of the frequency dispersion curve on the stratigraphic shear wave velocity difference is effectively improved, so that the detection capability of the urban s
