本文在分析卫星通信干扰威胁的基础上,讨论了利用扩频信号处理(包括直接序列扩频和跳频)、自适应天线调零以及星上处理等技术,以有效地改善干扰威胁情况下的通信可靠性。最后,提出了抗干扰系统设计最佳化的若干准则,并研究了实现逼近最佳准则的技术途径。 Based on the analysis of the threat of satellite communication interference, this paper discusses the use of techniques such as spread spectrum signal processing (including direct sequence spread spectrum and frequency hopping), adaptive antenna zeroing and on-board processing to effectively improve the threat of interference Communication reliability. Finally, several criteria for the design of anti-jamming system are proposed, and the technical approaches to achieve the best approximation are studied.
