摘要
由于大地信道稳定，低频透地通信被认为是最可靠的救急通信方式。对环状发射天线情形下分层大地的有关信道特性进行了探讨，以期为该系统设计及工程应用提供有益的指导。
The VLF Through the Earth Communication system is recognized as the most reliable way of conveying dispatching information due to its special transmission media. This paper investigates the propagating characteristics of the layered earth in a loop antenna case, the result can be served as a helpful guideline for the system design and application.
