以经典的双点源干扰模型为基础，简要说明了在双点源干扰下导引头的静态跟踪误差。在此基础上，研究了动态下的攻防对抗，建立了数学模型并仿真，得出了攻击误差。仿真分析了双干扰源功率变化时导弹的攻击轨迹和误差，以及功率不相等时干扰源间距和天线波束宽度对诱骗效果的影响。仿真结果表明：只要参数合适，非相干双点源干扰可以很好的诱骗导引头，达到保护目标的目的。

Based on the classical dual-source j amming model,the static tracking error angle of radar seeker under dual-source j amming is briefly explained.On this basis,dynamic attack-defense confrontation is re-searched,mathematical model and simulation are established,and the attack error is acquired.Missile’s attack traj ectory and error are analyzed by simulation,and decoying effect that is influenced by the length between two j amming sources and width of antenna beam when the dual-source power is unequal.Through simulating,as long as the parameters are appropriate,non-coherent dual-source j amming can well decoy radar seeker and protect the target.
