工程勘探瞬变电磁仪关键技术研究

Study of the key technology in TEM instrument

摘要: 瞬变电磁勘探法是工程勘探领域里新兴的一种很有前途的测量方法。但是作为一种重要探测工具,瞬变电磁仪的许多关键技术还没有解决,限制了瞬变电磁勘探法在工程勘探领域的应用。本文研究了瞬变电磁仪的硬件和软件设计中的关键技术,并提出了程控接收天线法和早期信号检测法等。

Abstract: Transient Electromagnetic Method (TEM) is a kind of promising measure method in the shallow geophysical soundings.As an important detecting tool, there are many key technology to be solved, So TEM soundings is limited in the shallow geologic structure exploration.In this paper, the key technology of hardware and software design in TEM.A new program-controlled antenna and early signal detecting are put forward.
