APPARATUS AND METHOD FOR HIGH SPEED SUBSURFACE INSPECTION OF BUILT INFRASTRUCTURE

摘要

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.

主权项

1. An apparatus for high speed inspection of built infrastructure, comprising:
a) an upper support; b) a housing containing an array of ground penetrating radar antennas aimed downward; c) non-stretchable straps attached between said upper support and said housing; d) said housing supported from below on a pair of skis spaced from a target surface by wear plates; e) said apparatus supported on a vehicle movable over said target surface to facilitate collection of data concerning structures beneath or behind said target surface.
