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。
Inter-satellite link interference is an important factor affecting the accuracy of link measurement. Anti-jamming performance analysis Link state space information and communications planning, analysis of different types of interference on the link probability of interference and interference strength, and finally get the link on different types of interference immunity. Based on the inter-satellite link model, combined with the link communication planning, the mutual interference and single-frequency interference that have a great influence on the link system are selected, and the interference characteristics of the system during the operation cycle are analyzed. It is verified that the link model and communication plan are less affected by mutual interference. The influence of strong ground disturbance on the system may cause the single satellite to work temporarily, but it will not affect the entire constellation performance.
