卫星通信抗干扰技术及其发展趋势研究

Research on Anti-Interference Technology for Satellite Communication and Its Development Trends

为进一步提升卫星通信质量,充分发挥卫星通信抗干扰技术的优势,从通信系统间干扰情况、电磁干扰、人为干扰3个方面分析卫星通信干扰的相关因素,讨论常见卫星通信抗干扰技术内容,合理应用天线抗干扰技术、限幅和线性化技术、星上处理技术、编码调制抗干扰技术以及扩展频谱抗干扰技术等共同提高卫星通信抗干扰水平,最后展望卫星通信抗干扰技术发展趋势。

In order to further improve the quality of satellite communication and fully leverage the advantages of satellite communication anti-interference technology,it is necessary to analyze the relevant factors of satellite communication interference from three aspects:interference between communication systems,electromagnetic interference,and human interference.The content of common satellite communication anti-interference technologies is discussed,and antenna anti-interference technology,limiting and linearization technology,and onboard processing technology are reasonably applied Encoding modulation anti-interference technology and spread spectrum anti-interference technology jointly improve the anti-interference level of satellite communication,and finally look forward to the development trend of satellite communication anti-interference technology.
