Geophysical methods are important tools for a wide range of geological, hydrogeological, and engineering investigations. Conventional processing techniques for electromagnetic tools often use approximations that may be either inappropriate or only provide limited resolution. Higher resolution images can be derived by using more sophisticated approaches that(More)
There is a new method to measure the thickness of an ice layer of a lake. Contrary to applying common offset GPR measurements, no calibration measurement is needed and contrary to the most conventional method to drill a hole, the ice layer is not destroyed. Therefore no water overflows the ice which is an advantage if activities take place on the frozen(More)
Ground Penetrating Radar (GPR) has found widespread application for the non-invasive characterization of the subsurface. Nevertheless, the interpretation of GPR measurements remains difficult in some cases, particularly when the subsurface contains thin horizontal layers with contrasting dielectric properties that might act as waveguides for electromagnetic(More)
