摘要:

推导得出了线极化和圆极化状态下评估极化失配因子的数学模型,基于西安地区降雨率测量数据和北京、三亚地区统计降雨率数据,给出了西安、北京、三亚地区Ka频段地空链路雨致极化失配因子统计特性,本文的研究结果对于Ka频段无线链路功率储备预算和性能评估具有重要的理论意义和实用价值。

The formulae for estimating polarization mismatch factor of linear and circular polarization waves are derived. The statistical characteristics of polarization mismatch factor at Ka bands for earth-space link are given in Xi’an, Beijing, Sanya, China, based on the measured rain-rate data in Xi’an and the statistical rain-rate data in Beijing and Sanya, China. The results presented in this paper are significant and practical for pre-calculating power reserve and pre-estimating link performance at Ka bands.
