为了克服传统地波通信干扰效能评估模型的不足,提出了一种球形地面上地波干扰效能评估模型。基于干信比的计算,分析了传统效能评估模型的不足;给出了球形地面上干扰效能评估模型的详细计算步骤;结合实例对两副天线的干扰效能进行仿真计算,并绘制了干扰压制区和通信暴露区分布图。文中干扰效能评估模型比较符合实际,对相关领域的计算有一定指导意义。
In order to overcome the shortcomings of the traditional ground-wave communication interference effectiveness evaluation model, a model of ground-wave interference performance evaluation on spherical ground is proposed. Based on the calculation of dry credit ratio, the insufficiency of the traditional performance evaluation model is analyzed. The detailed calculation steps of the interference performance evaluation model on the spherical ground are given. The interference performance of the two antennas is simulated with examples and the interference suppression area And communication exposure area distribution map. In this paper, the interference effectiveness evaluation model is more realistic and has certain guiding significance for the calculation in related fields.
