摘　　要：角跟踪雷达导引头广泛采用单脉冲角跟踪技术。针对传统干扰方法难以干扰单脉冲角跟踪技术的问题,介绍了"交叉眼"干扰的基本原理,推导了对单脉冲角跟踪雷达实施"交叉眼"干扰时跟踪角误差的数学模型,分析了干扰源功率比、干扰源相位差、"交叉眼"干扰搭载平台回波等因素对干扰效果的影响并进行了计算机仿真。仿真结果表明,正确使用"交叉眼"技术,能够产生大于两干扰源在雷达处张角的角度误差,致使雷达导引头跟踪在两干扰源张角之外的虚假目标。The technology of monopulse angle-tracking is adopted widely by angle-tracking radar seekers. Aiming at the problem that traditional methods cannot disturb the technology of monopulse angle tracking easily, the principle of cross-eye jamming is described . The mathematical model of angle error when cross-eye jamming is released to monopulse angle-tracking radar seekers is inferred. The impact of the power ratio of jamming sources, the phase error of jamming sources and the echo of cross-eye jamming platforms is analyzed and simulated. Simulation results show that the cross-eye jamming can cause an angle error larger than the splaying angle between the two jamming sources and the false target out of the jamming sources will be tracked by radar seekers.
