摘要
通过分析影响卫星通信系统的不同外部干扰,找出应对措施。对河南地球站的雨衰进行估算,为日常工作提供计算参考值。依据地球站发现和分析干扰的常用手段,归纳导致下行信号接收质量恶化的原因及应对措施,并总结出处理流程。
By analyzing the effect of external interference of satellite communication system , it finds the count-er-measures .Calculating the rain attenuation estimation of Henan Earth Station provides reference data for daily work.According to the interference measurements which are often used in earth station , it concludes different reasons which cause deterioration of the quality of the received signals .
