Abstract

An experimental wideband chaotic ground penetrating radar is proposed to locate underground pipes. A chaotic signal with a bandwidth of 1.56 GHz is utilized as the probe signal. The localization of the pipes is achieved by correlating the chaotic echo signal with its delayed duplicate and back-projection algorithm. Experimental results demonstrate that plastic pipe, metallic pipe, and multiple pipes can be located with a range resolution of 10 cm. Limited by the height of the sand, the detectable range is estimated to be 0.7 m for both the plastic pipes and the metallic pipes when the transmitting power is -12 dBm. The proposed system has the potential to detect buried pipes, and it is suitable for geological and civil engineering applications.

摘要

提出了一种用于定位地下管道的实验性宽带混沌探地雷达。利用带宽为1.56 GHz的混沌信号作为探测信号。通过将混沌回波信号与其延迟副本进行相关以及采用反向投影算法来实现管道的定位。实验结果表明，塑料管道、金属管道和多根管道都能够以10 cm的距离分辨率进行定位。受沙子高度的限制，当发射功率为-12 dBm时，塑料管道和金属管道的可探测范围估计均为0.7 m。所提出的系统具有探测地下埋藏管道的潜力，适用于地质和土木工程应用。
