Development of a pipe location system, phases 2 and 3
Abstract
Capability for high resolution imaging of buried gas pipe has been demonstrated under this research project. A synthetic aperture focusing technique (SAFT) was combined with ground penetrating radar for this application. Resolution of objects separated by as little as 2 to 4 inches at depths of four feet was obtained. The technology appears capable, with some refinement, of providing the basis for field mapping systems. Extensive research was conducted to apply both radar and acoustic methods to the problem since the dual capability would accommodate a greater variety of soils. These methods were evaluated in conjunction with holographic imaging as well as SAFT.
