چکیده
Gas pipeline network is the foundation and guarantee of urban energy transmission. Accurate pipeline location and buried depth are important information for gas company operation management and establishment of GIS system. In recent years, PE (polyethylene) pipelines have been widely used in medium and low-pressure town gas transportation due to their strong anti-corrosion capabilities. Because PE pipes are inert materials, non-metallic, non-conductive, and non-magnetic, determining their location in underground spaces has always been pipeline detection difficulties in the field. By analyzing the detection principle and positioning method of ground penetrating radar, the imaging characteristics of PE pipes without tracers in the ground penetrating radar and the method of distinguishing them from steel pipes and cables are analyzed. The research results have improved the detection accuracy of the PE pipeline, established a gas pipeline network information system, and ensured that the pipeline detection operation has theoretical and practical significance. The aim of this article is analyzing the working principle of GPR, and also efficiency of GPR for detecting the gas PE pipeline in three districts at Iranshahr. Due to the huge number of radargrams obtained in the area, some of them were selected to present in this article.

Abstract
Gas pipeline network is the foundation and guarantee of urban energy transmission. Accurate pipeline location and buried depth are important information for gas company operation management and establishment of GIS system. In recent years, PE (polyethylene) pipelines have been widely used in medium and low-pressure town gas transportation due to their strong anti-corrosion capabilities. Because PE pipes are inert materials, non-metallic, non-conductive, and non-magnetic, determining their location in underground spaces has always been pipeline detection difficulties in the field. By analyzing the detection principle and positioning method of ground penetrating radar, the imaging characteristics of PE pipes without tracers in the ground penetrating radar and the method of distinguishing them from steel pipes and cables are analyzed. The research results have improved the detection accuracy of the PE pipeline, established a gas pipeline network information system, and ensured that the pipeline detection operation has theoretical and practical significance. The aim of this article is analyzing the working principle of GPR, and also efficiency of GPR for detecting the gas PE pipeline in three districts at Iranshahr. Due to the huge number of radargrams obtained in the area, some of them were selected to present in this article.
