甚低频发信天线辐射场强计算与测量方法研究OACSTPCD
Method of Field Strength Measurement and Calculation of VLF Antenna
为了评估甚低频发射天线的辐射性能，需对甚低频信号辐射场强进行测量。论文对甚低频场强测量与计算相关问题进行了深入探讨，提出了一种计算场强的新方法，并且分析了误差原因；对静电场和感应场的影响也进行了分析。基于波跳理论，提出了在一定测试距离范围内，通过测量场强进而推算辐射场和辐射功率的方法。距离达到40km 时，场强是一跳天波和辐射波的叠加，在约40km 以内时天波场的影响则不大。
The measurement of the radiated field strength of a very low frequency signal was needed for evaluating the transmitting antenna .In the paper ,some issues relevant to the measurement and calculation of the radiated field strength were researched deeply ,a new method to calculate field strength was introduced ,and the errorwereanalyzed .The effect of the electrostatic field and induced field were also taken into consideration .Based on wave‐hop theory ,the m…查看全部>>
