摘　　要：非金属管道在油气田和城镇环境中被广泛应用,但是非金属管道在长期服役过程中由于示踪信号丢失,导致管道难以定位,给管线维护和后续施工带来了严重的困扰。探地雷达作为地下目标探测的主要方法之一,在对非金属管道探测和定位过程中,受到非金属管道反射回波信号微弱、地下干扰信号较多等因素的限制。针对上述问题,采用并行等效采样技术设计了一种新型的探地雷达采样电路模块,并通过接收电路和高性能示波器对数据采集结构进行对比分析,验证了该接收电路的有效性和准确性。研究成果可提高探地雷达的信号采集率,从而提高成像分辨率,为埋地非金属管道的探测和定位提供一种新的解决方案。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 pipeline maintenance and subsequent construction.Although ground Penetrating Radar(GPR)is used as one of the main methods for underground target detection,it is suffered limitations such as weak echo signals and too many interference signals in detection.Aiming at the above problems,this research designs a new non-metallic pipeline detection device,adopting parallel equivalent sampling technology to design a new receiver circuit module for ground-penetrating radar.The correctness of the function of the receiver is verifies through the comparative 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.
