Overview of Anti-Jamming Methods in Airspace of Microwave Tactical Communication System

针对日益复杂恶劣的现代战争电磁环境,提出了基于相控天线的微波战术通信系统干扰测向与抑制方法。分析了空域抗干扰应用需求,提出了波束切换阵/模拟相控阵天线比幅测向法、窗函数加权及波束陷零干扰抑制方法。通过干扰测向原理阐述、窗函数性能定量分析、干扰陷零模拟仿真,证实了空域抗干扰的可行性和有效性。

In view of the increasingly complex and harsh electromagnetic environment of modern warfare, this paper proposes a method of interference orientation and suppression based on the phased antenna array in microwave tactical communication systems. The application requirements of spatial anti-jamming are analyzed, and the beam switching array/analog phased array antenna ratio measurement method, window function weighting and beamforming null interference suppression are proposed. The feasibility and effectiveness of airspace anti-jamming are verified through the description of interference direction principle, quantitative analysis of window function performance and interference nulling simulation.
