The problem of passive geophysical monitoring of transport objects using acoustic and three-component seismic oscillations is considered. The solution is based on the application of spectral-time analysis, the method of spectral-polarization processing, the selection of informative frequencies of oscillations and the determining the direction finding on the object. The azimuthal orientation of the major axis position of the scattering ellipse obtained by polarization processing makes it possible to determine the direction finding. Numerical estimates of the accuracy of problem solving in a field experiment have been obtained. The proposed approach is based on consideration of the spatial-frequency characteristics of the object and its seasonal variation.

The work is related to numerical estimation and comparative analysis of microseismic and acoustic noise levels in transport polygon conditions. The aim of the work is to study and further define the difference between the signal and noise to improve the ability to detect poorly distinguishable events, as well as to study the propagation features of the interrelated seismic and acoustic wave fields. It is related to the fact that wave processes generated by many natural and anthropogenic sources are conjugate nature. In particular, it is related to simultaneous propagation of seismic waves in the ground and acoustic waves in the atmosphere. It determines expediency of taking into account simultaneously parameters of both types of waves in the tasks of geophysical monitoring of the environment, as well as in solving some applied problems of seismics and acoustics.
