THE VLF FIELD ON THE SURFACE OF THE SEA GENERATED BY THE SPACEBORNE TRANSMITTER AND ANTENNA

摘要: 星载的VLF/ELF发射装置用于对潜通讯时,天线是位于400km高度的电离层F层中的垂直线天线。在天线理想化为一个电偶极子,电离层理想化为一个均匀锐边界各向异性等离子体模型下,分析讨论了VLF发射装置在海面上产生的场。Abstract: The recent space technology is capable to design a spaceborne VLF/ELFtransmitter and antenna for the communications to submarines, in this.case, the antenna is a vertical wire in the F-layer of the ionosphere at a height of 400km. Forsimplicity, the antenna is idealized as a dipole, the ionosphere is idealized as ahomogeneous anisotropic plasma with sharp boundaries, the VLF magnetic fieldon the sea surface is analyzed and calculated.
