Non-metallic pipelines are widely used in oil and gas field and urban environment.However,due to the loss of tracer signals in non-metallic pipelines during long-term service,it is difficult to locate buried non-metallic pipelines,which brings serious troubles to pipe-line maintenance and subsequent construction.Although ground Penetrating Radar(GPR)is used as one of the main methods for under-ground target detection,it is suffered limitations such as weak echo signals and too many interference signals in detection.Aiming at the a-bove problems,this research designs a new non-metallic pipeline detection device,adopting parallel equivalent sampling technology to de-sign a new receiver circuit module for ground-penetrating radar.The correctness of the function of the receiver is verifies through the com-parative analysis of the results of the data acquisition by the receiver and the high-performance oscilloscope.The results of this research can improve the signal acquisition rate of ground-penetrating radar,thus improve the imaging resolution and provide a new technical solution for detecting and positioning buried non-metallic pipelines.
