摘　　要：干扰定点在地球同步轨道的中继卫星,可以大大降低其数据传输和航天器测控的时效性和有效性。与通信卫星天线波束指向相对固定不同,中继卫星需要跟踪空间运动的航天器,星间天线指向随机且覆盖范围较小,需要研究完全不同的干扰策略和实施方法。伴星干扰是最有效的中继链路干扰策略,在此基础上确定了中继链路干扰目标选择原则和干扰卫星轨道,设计了干扰伴星进入中继卫星干扰区域的轨道控制策略和实施方法。研究结果表明,干扰伴星能够进入中继星星地天线的主瓣并保持情况下,干扰中继前向链路最有效;干扰伴星只能在轨道自由漂移的情况下,干扰中继返向链路效果最有效。针对干扰伴星不同干扰方式,提出应对抗干扰措施。Jamming a Tracking and Data Relay Satellite(TDRS)at a fixed point in the geosynchronous orbit can greatly reduce the timeliness and effectiveness of its data transmission and spacecraft TT&C.Unlike the communication satellite which has a relatively fixed beam pointing,the TDRS is required to track the spacecraft in motion,so the intersatellite antenna pointing is random and the coverage area is small.It is necessary to study completely different jamming strategies and implementation methods.The analysis results show that the accompanying satellite jamming is the most effective jamming strategy for relay links.Based on this,the principle of selecting jamming targets for relay links and the jamming satellite orbit are determined,and the orbit control strategy and implementation method of jamming satellite entering the jamming area of TDRS are designed.The results show that if the jamming satellite can enter the main lobe of TDRS antenna and keep in it,jamming forward relay link is the most effective,and jamming return relay link is the most effective when the jamming satellite can only drift freely in the orbit.The anti-jamming measures are put forward according to different jamming modes of jamming satellite.
