A sensor stabilizing technology of air cushion for pile detection

Abstract

The noise signals are generated from subsurface sensors in proportion to the inclination and distance from the surface of the ground. The dynamic ranges of subsurface sensors are able to keep their characteristics against the noises with a stabilizing apparatus. This paper describes an air-cushion technology which stabilizes subsurface sensors and improves the characteristics for the detection of buried objects. The performance of a newly developed system was clearly demonstrated. The experimental results and some discussions are also shown in this paper.
