Abstract
A ground penetrating radar antenna array is consistently maintained at a spacing of less than or equal to about 4 inches above the target surface. As a result, the antenna array may be moved up to 75 mph while maintaining accuracy of data collection. The apparatus includes a wooden support from which non-elastic straps are suspended. The straps are attached to a housing containing the ground penetrating radar antenna array and receiver. The housing is supported from below by a pair of skis that have wear plates attached to their undersides with the wear plates engaging the target surface. The wear plates maintain the distal ends of the antennas within the antenna array at a spacing from the target surface of less than or equal to 4 inches, preferably 3.75±0.25 inches. The method of operation is also disclosed.
