本文以分析对流层散射通信中的基本传输损耗、天线平面波增益和天线介质耦合损耗等与工作频率的关系为基础,介绍了求解最佳工作频段的三种方法,并详细推导了最佳工作频率的计算公式。然后以天线口面直径为参变量,计算了对应不同通信距离的最佳工作频率。文末还指出了影响选择最佳工作频段的若干因素。
Based on the analysis of the fundamental transmission loss, the plane wave gain and the coupling loss of the antenna medium with the operating frequency in the troposcatter communication, this paper introduces three methods to find the best working frequency band, and deduces the best working frequency Calculation formula. Then the diameter of the antenna port is taken as the parameter to calculate the best working frequency corresponding to the different communication distance. At the end of the article also pointed out that the impact of the selection of the best operating frequency band of several factors.
