Abstract The underground pipeline detection with small intervals and non metal are two major problems in current pipeline detection, plus the complicated layered medium and the influence of interference factors, thus increases the difficulty of the pipeline detection,and it is difficult to judge target abnormal bodies on radar section. In order to locate the target line and improve interpretation accuracy, in view of the two big detection problems and interference factors, we uses GprMax software and Matlab language to simulate pipeline models under complicated layer condition. The simulation results indicates that the pipeline lateral resolution of 250 MHz antenna frequency is 50 cm in the case of 1m depth. Radar reflection wave image of mental and non mental are different.Therefore,based on these information to judge the filling material and the size of pipeline. The results of simulation can play a substantive role in actual complicated underground pipelines detection.
