Summary:The invention relates to the technical field of geological exploration, in particular to a surface wave exploration method for separating a wave field through frequency Hankel transformation and a related device. The method comprises the steps of firstly collecting ground vibration of an explored area, then calculating a corresponding Green function of a stratum of the explored area, then separating a divergent wave frequency spectrum from the Green function through frequency-Hankel transformation, and finally obtaining a stratum structure where the explored area is located through the divergent wave frequency spectrum. According to the method, the wave field Green function is separated by adopting the frequency Hankel transformation, so that the separated divergent wave spectrum does not contain the convergent wave, the noise interference of the convergent wave on the frequency dispersion spectrum is avoided, and the stratum structure finally inverted according to the frequency dispersion spectrum is closer
