摘要

Abstract: The United States Department of Energy's Special Technologies Laboratory (STL) staff has been actively involved with ground penetrating radar technology since 1968. STL has developed a stepped FM-CW Ground Penetrating Radar (GPR). The initial application of this unit was the detection and imaging of unexploded ordnance. Since this time the target types have been expanded to subsurface storage containers, pipes and utility cables. Additionally, some field tests have been conducted where nonmetallic targets were of interest. Four case studies on the detection of buried ordnance and hazardous waste storage containers are discussed in this paper. A brief description of the STL GPR unit is presented.!7
