| 摘 要： | 星间链路中干扰是影响链路测量准确度的重要因素.抗干扰性能分析可以通过链路卫星空间状态信息和通信规划,分析不同类型的干扰对链路的干扰概率和干扰强度,最终得出链路对不同类型干扰的抗干扰能力.基于星间链路模型,结合链路通信规划,选择对链路系统影响较大的互干扰和单频干扰,分析了系统在运行周期内的干扰特性.经验证得出该链路模型和通信规划受互干扰影响较小,地面强干扰对系统影响可能导致单颗卫星短暂无法正常工作,但不会对整个星座性能产生影响.

| Abstract: | Jamming within inter-satellite link is the important factor influencing the measuring accuracy of the link system.According to the state space information of link satellites and communications planning,anti-jamming performance analysis figures out the interference probability and the interference intensity,and eventually,anti-jamming ability of the link to various types of disturbances is demonstrated.The analysis is based on the model of the inter-satellite link.Through combining the link communications pl... |
