Abstract
Current approaches for detecting water saturated regions in a rockmass uses geophysical methods, such as electrical resistivity tomography (ERT), self-potential (SP), and seismic imaging to spatially detect and map the rock water content in underground mines. However, all these approaches are contact based. Present disclosure provides a non-contact method and system for inspecting and detecting water saturated regions in a rockmass. The system uses coherent radar generated range-compressed data collected from a plurality of rock specimens for generating a generalized calibration function using a range doppler algorithm and a phase tracking algorithm. The system then uses the generated generalized calibration function for estimating water saturation of a target rockmass along with the use of the RDA and the phase tracking algorithm.
