摘　　要：单脉冲雷达天线的差波束指向和灵敏度通常受2个通道的幅相不平衡性影响,通过仿真计算和测试,在某些情况下,天线极化形式也会对差波束指向带来影响,例如斜45°极化。文中对几种典型模型进行了仿真、对比,并结合测试情况,分析了这种现象的成因、产生条件、对雷达性能的影响,最后给出了几种解决方案。The offset beam directionality and sensitivity of the monopulse radar are mainly influenced by the gain-phase imbalance of the two channels.Based on simulation and test,the offset beam directionality can be also influenced by the polarization of the antenna in some situations,such as the 45° inclined polarization.In this paper some typical models are simulated and compared.The genesis,conditions and the influence on radar are analyzed.Some solving methods are introduced in the end.
