摘要
由于GEO轨道资源有限,GEO通信卫星之间距离缩小,不可避免相互干扰。分析了空间信号传输链路的损耗,研究了目前GEO通信卫星所采用的喇叭天线和抛物面天线的信号特征,建立了上行链路信号干扰模型,最后基于X频段和Ka频段的GEO通信卫星干扰进行了建模与仿真,验证了干扰的有效性。
The distance between different GEO communication satellites is decreasing due to the finite GEO orbit, so the mutual interference is hard to avoid. Both the link wastage of space signal and the signal characters of horn antenna and paraboloid antenna on GEO communication satellites are analyzed. The model of effective disruption to the up-link is established. Based on the frequency bands of X and Ka, modeling and simulation of effective disruption is accomplished, which proves effec- tiveness of the disruption.
