摘要
通过分析天线场地等效视电阻率与极低频水平发射天线性能的关系,指出沿天线架设方向视电阻率的长度加权平均值可作为评价极低频发射天线场地好坏的指标,给出了非均匀大地沿天线路径等效视电阻率的计算方法.
A practical extremely low frequency （ELF） horizontal antenna requires a site of high effective resistivity. This paper describes the relation between the site effective apparent resistivity and the performance of the horizontal transmitting antenna. It is proposed that the length-weighted average of the apparent resistivity along the antenna is a key parameter of the ELF transmitting antenna site characterization. A calculating method for the effective apparent resistivity along the antenna at a inhomgeneous ground is given.
