f Development of a Dual Mode Ground Penetrating Radar (GPR) for Deep Imaging to the Sand Dunes and Weathering Layers Thickness

A low frequency Ground Penetrating Radar has been developed and, more particularly, a dual mode GPR. The dual mode operation interleaves a short transmit pulse with a sequence of longer spread spectrum pulses. The dual mode GPR allows for rapid measurement and imaging the geological structures or layer depths, such as sand dunes more than 120m depth, and weathering patterns of geological features.
