Abstract
Suppression of surface wave interference is a necessary step in the processing of land seismic data. Traditional methods, such as single-channel band-pass filtering and multi-channel FK filtering, often fail to separate the desired signal from interference. The proposed method of suppressing surface waves based on the analysis of the main components of the wave field in the time-frequency domain shows the best results. The method is based on the model of surface wave propagation in horizontally layered media, however, numerical experiments were carried out demonstrating the applicability of the method in horizontally heteronode three-dimensional media. A software package "PF Seism" has been developed and registered, which implements the proposed method for suppressing surface waves.
