Abstract
The application of signal energy parameters to estimate the motion of objects with continuous influence on soil in systems of passive seismic location is considered. Statistics for measured values of signal powers with account for energy properties of the medium are proposed. The influence of displacement of the object on the ratio of signal powers on different sensors is analyzed. The results of testing the algorithm for estimating the parameters of the trajectory of rectilinear motion of a car are given.
