Abstract
Ground penetrating radar is a technique that is noted for its potential for high spatial resolution. This compensates somewhat for the relatively modest ranges usually achieved in geological media. High resolution is achieved by generating radio frequency pulses in the VIS to UHF band with band-width to centre-frequency ratios approaching unity. Consequently, subsurface radar pulses in the time domain have pulse widths of the order of nanoseconde providing, in principle, goud definition of subsurface interfaces .
