Spatial autocorrelation method is based method for the dispersion curves analysis of microtremors, which is being paid more and more attention because of its convenience and efficiency, and no disruption to the environment. In this paper, the homogeneous medium and layered media are studied by numerical simulation. First, the different array radii are used to receive signals in the homogeneous medium model, and the influence of the radius on the depth of detection is obtained. Secondly. We set a different number of field sources, The influence of the number of field sources on the dispersion curve is analyzed. Finally, the dispersion curve is extracted for the layered medium and compared with the theoretical dispersion curve, which show a well consistent.
