摘　　要：交叉眼干扰技术是针对单脉冲跟踪系统实施角度欺骗的一种重要手段。交叉眼干扰有效实施的关键因素是使得到达被干扰雷达的天线口面的两路干扰信号幅度相等、相位相反,其中相位相反是较难实现因素。论文对非反向天线实现结构和反向天线实现结构进行了分析得出了两个结论。一是非反向天线具有实现简单,可对抗无源雷达的优点,但是无法保证干扰信号为反相并且干扰有效扇区较小;二是反向天线结构可以保证到达被干扰雷达的干扰信号无波程差引入的相位差,能够保证干扰信号相位为反相,但是存在收发隔离和支路匹配的问题。Cross-eye jamming technology is an important means of implementing angle deception for single pulse tracking sys-tems.The key factor for effective implementation of cross-eye jamming is to ensure that the amplitude of the two interference signals reaching the antenna interface of the jammed radar is equal and the phase is opposite,among which the phase is the more difficult factor to achieve.This article analyzes the non-reverse antenna implementation structure and the reverse antenna implementation structure,and draws two conclusions.One is that non reverse antennas have the advantages of simple implementation and can coun-ter passive radar,but cannot guarantee that the interference signal is in reverse phase and the effective interference sector is small.The second is that the reverse antenna structure can ensure that the interference signal arriving at the jammed radar has no phase dif-ference caused by wave path difference,which can ensure that the interference signal is in reverse phase.However,there are issues with transmission isolation and branch matching.
