用峰位移动法识别地下水平近距金属多管线分布

Identification of Multiple Underground Metal Pipes in Horizontal Short Distance by Shifting Peak Position

通过对电磁感应式地下金属管线探测仪（简称探测仪）发射机机械结构的改进，本文提出了一种提高这类探测仪水平分辨能力的新方法，并用天线理论分析了这种方法的可行性。理论分析和实际探测表明，文中给出的方法对于提高探测仪水平分辨能力十分有效。

This paper gives one new method for raising the horizontal resolving power of electromagnetic induction underground metal pipe detector through improving the mecha nical structure of the transmitter of the detector.The paper also analyzes the feasibility of the method by means of antenna theory.The theoritical analysis and real detections show that the method described in the paper is very effective on raising the horizontal resolving power of the detector.
