摘　　要：调制电离层激发ELF/VLF电磁波为深海潜艇通信提供了一种可能的天线产生方式.本文介绍了国外电离层ELF/VLF电磁波激发理论的研究情况和实验结果,引进了HF电磁波加热电离层理论和物理模型并介绍了相应的实验结果,讨论了加热系统的激发效率提高问题.展望了该领域的未来研究方向,并提出了在我国的地理条件下激发电离层ELF/VLF电磁波需要解决的问题.Excitation of ELF/VLF electromagnetic waves by modulating the ionosphere current provides a possible way of antenna generation for deep sea submarine communication. The theory of ELF/VLF wave excitation in the ionosphere and the experimental results abroad are presented in this paper. The ionospheric heating theory by HF electromagnetic waves and the physical model and the experiment results are described. Also the excitation efficiency of the heating system is discussed. The future research direction in this field is prospected and the problems need to be solved are proposed to generate ELF/VLF waves in the ionosphere under the geographical conditions of our country.
