干扰是机载雷达在作战使用中面临的一个重要挑战,抗干扰能力成为评价机载雷达性能的关键指标。文中介绍了机载雷达面临的干扰环境,总结了机载雷达抗干扰的思路,指出基于干扰环境感知的抗干扰策略存在的优势。进一步介绍了常用抗干扰措施的机理和实施方法,针对突出的主瓣干扰难题,重点阐述了近年来日益受到关注的极化抗干扰和协同抗干扰技术。最后,面对干扰技术发展带来的挑战,分析了机载雷达抗干扰技术的发展趋势。

Jamming is one of the most important challenges airborne radar faces in the battle use, and so the anti-jamming capability becomes a key parameter used to evaluate the performance of airborne radar. First, the jamming environment that airborne radar encounters is introduced in this paper, then anti-jamming mind and advantages of anti-jamming strategy based on jamming environment are described. Further principles and implementations of some frequently-used anti-jamming methods are presented. Specially, recently focused anti-jamming techniques with polarimetry and with multistatic radar collaboration aimed at main-lobe jamming suppression are detailed. Finally, due to the progress of the jamming technique, future development tendency on the anti-jamming technique is analyzed.
