摘　　要：回顾了利用大功率的高频电磁波调制电离层自然电流产生ELF/VLF电磁辐射的发展情况。介绍了典型加热设备的系统参数配置情况以及地面和卫星上检测ELF/VLF信号的实验结果。总结了提高ELF/VLF产生效率等问题的进展情况,尤其是"波束扫描"技术的理论研究和应用发展。提出了该技术下一步需要研究及解决的问题。The development of ELF （Extremely Low Frequency）/VLF （Very Low Frequency） electromagnetic radiation generation from the ionosphere natural current modulated by powerful High Frequency waves is reviewed. The system parameter configu- rations of the typical heating facilities and the detection results of ELF/VLF signals on both ground and satellite are introduced. The research of raising ELF/VLF generation efficiency is summarized, especially the theoretical research and application of “beam painting” technique. The problems to be studied and solved for the next step are proposed.
