摘要/Abstract

摘要： 针对地球静止轨道（GSO）卫星系统在卫星和地球站布设中的同频干扰评估问题，设计了地球站及卫星的全球分布对下行和上行通信链路的干扰评估场景，以及考虑波束业务特征影响的多条链路的集总干扰场景，构建了不同场景下的干扰评估和分析计算的模型，提出了一种基于干扰函数极值的评估方法。所提方法通过建立干扰系统地球站的随机分布集合和受扰系统的干扰函数，结合国际电联（ITU）提供的全球地形数据、天线波束参数、电磁波传播模型，能够实现对2个GSO卫星系统间的卫星轨位和地球站布设的定量化计算分析。采用所提方法对位于47°E±6°的GSO卫星系统、位于（23°N，26°E）地球站的同向下行链路，以及位于（23°N，26°E）的地球站对26°E±6°的GSO卫星系统的同向上行链路的干扰情况进行了定量化计算。结果表明：在卫星轨位间隔为2°时的干扰噪声比值为-12.29 dB，与ITU建议书中规定的-12.2 dB的限值之间的误差为0.7%，证明了所提方法的有效性和可行性。所提方法还可以统计GSO卫星系统在任意角度间隔和全球布设场景下的干扰分布情况，对于干扰评估和规避措施的制定具有一定的借鉴意义。

Abstract: Aimed at the issue of co-channel interference estimation in the Geostationary Satellite Orbit (GSO) system layout, the interference assessment scenarios were designed with the global distribution of earth stations and satellites for downlink and uplink and the integrated impact of beam service characteristics for multiple links. The interference estimation and analytical calculation models for the global distribution of the GSO system were established. An evaluation method based on interference function extremum was proposed. By establishing the random distribution set of the interference earth stations and the function of the interfered system, combined with the global terrain data, antenna beam parameters, and electromagnetic wave propagation model provided by International Telecommunication Union (ITU), the method could realize the quantitative calculation and analysis of satellite orbital and earth station layout between two GSO systems. The method was applied to co-directional downlink and uplink interference scenarios for quantitative calculation, with GSO satellites at 47°E±6° and earth stations at the (23°N, 26°E) for downlink, and GSO satellites at 26°E±6° and earth stations at the (23°N, 26°E) for uplink. The results show that the interference-to-noise ratio value is -12.29 dB with 2° orbital interval, and the error is 0.7% with the limit -12.2 dB specified in the ITU Recommendation, which verifies the effectiveness and feasibility of this method. The method can also calculate the interference distribution of GSO system in any angular interval and global deployment scenario, which has certain reference significance for making interference assessment and avoidance measures.
