Physical Experiments and Stochastic Modeling to Clarify the System Containing the Seismic Source and the Ground

Abstract

The nonlinearity of the system containing the source of seismic energy and the ground creates a difficulty for application of geophysical methods. The initial reason is in a distortion of signals radiated by the source. In this article the results of physical experiments using of an impulse source have been investigated. It has been demonstrated that in order to get a reliable Earth’s images is necessary to process signal series records from repeated experiments instead of traditional using of the record of one selected signal. The proposed technique is based on an application of the method of microseismic sounding, stochastic modeling and calculation of arithmetic mean values. The technique can be extended for other sources of seismic energy, where the radiated signal can be transformed to series of impulses.
