Abstract
The article considers methods for solving problems of geophysical monitoring of the environment in relation to powerful pulsed sources - quarry explosions, rocket remnants falling on to the ground of during satellite launches, meteorite fragments, etc. The general idea of the study is formulated as solving an inverse problem of restoring the source parameters based on its seismic and acoustic waves. Numerical modeling and experimental studies of the proposed methods for assessing the accuracy of spatial localization of sources are carried out on an example of using calibration spatially distributed explosions.
