摘　　要：现代雷达采用了旁瓣匿影技术(SLB),使传统方式的旁瓣干扰几乎失去效果。根据雷达旁瓣匿影(SLB)的设计原理和工作特点,提出了一种基于天线旁瓣相位特性破坏雷达SLB的干扰技术。即通过精确调制双点源的方式破坏雷达主、辅天线之间的平衡,使雷达SLB的功能失效。理论分析证明,该方法对于破坏雷达旁瓣匿影有明显的干扰效果。The technology of sidelobe blanking is adopted with modern radars, which makes sidelobe jamming in traditional mode lose its effect completely. A method is proposed to counter radar sidelobe blanking according to the basic principle and working characteristic of radar sidelobe blanking and antenna phase patterns characteristic. The double-point jamming which is modulated accurately to break the balance between main antenna and assistant antenna can deactivate radar sidelobe blanking. The theoretical analysis results show that this method is very effective to counter radar sidelobe blanking.
