Analysis of variance amplitudes of signals for detecting structural permafrost heterogeneities by ground penetrating radar
The possibility of using the variance amplitude of GPR signal has been considered for investigating the structural features of the geological environments of permafrost. The variance values of the investigated GPR data of the properties and the state of soil areas of alluvial gold and diamonds in Yakutia province in Siberia have been calculated. It is established that the increase of the variance amplitudes of signals is characterized by the appearance of new reflection boundaries and the presence of geostructural rock mass heterogeneity. This is due to an increase in soil moisture and violation of the rock mass. Analysis of the features of the change the variance amplitudes of signals in the rock section allows us to define the type of geological heterogeneity and permittivity of rock. The proposed method of statistical analysis of GPR data simplifies the interpretation and allows us to automate the search for irregularities of the physical properties of rocks using specially developed software.
