Detection and Direction Finding of Transport Objects in Seismoacoustic Observation Systems

Abstract

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.
