采用自适应调零天线能够有效增强卫星通信系统的抗干扰能力,但也会出现因干扰处于卫星覆盖区而导致调零区用户通信中断的情况。本文提出卫星智能调零技术,以信息通过量最大为准则,通过对干扰情况的判决,确定自适应调零天线的应用策略。通过比较与不采用调零和常规调零技术体制的系统,分析和评估了智能调零技术体制的综合效能,说明智能调零技术能够进一步优化卫星通信系统的抗干扰性能。
Adopting adaptive zeroing antenna can effectively enhance the anti-jamming capability of satellite communication system, but there may also be a situation where user communication in zeroing zone is interrupted due to interference in the satellite coverage area. In this paper, the intelligent satellite zeroing technology is proposed. With the maximum information throughput as the criterion, the application strategy of adaptive zeroing antenna is determined through the judgment of the interference situation. By comparing and not using the system of zeroing and conventional zeroing system, this paper analyzes and evaluates the overall performance of the intelligent zeroing system, which shows that the intelligent zeroing technology can further optimize the anti-jamming performance of the satellite communication system.
