NSCPHD1047 High-resolution imaging of the subsurface using georadar methods

Radar methods are being increasingly used in the investigation of near-surface layers, and they now play a central role in characterization of subsurface variations in, for example, petrophysical parameters, geological structures and layering, water content, and fluid/gas flow patterns. The course presents and discusses basic theory behind the radar method, system developments, forward and inverse modeling schemes and practical applications.

In the first part of the course, we will describe fundamentals regarding the physical background of the radar method. A series of papers describing elementary theoretical aspects and applications of the method will be discussed. Subsequently, forward modelling algorithms, wavefield inversion, and stochastic data integration methods will be discussed. Fieldwork with a full day of data acquisition will be conducted in the middle of the course. In the final part of the course, we will work with hands-on problems regarding processing of acquired data. The processing will include frequency and frequency-wavenumber (F-K) filtering and fundamental aspects of migration.
