Abstract
Cross-eye jamming is a technique used for deceiving the angle measurement of monopulse radars. Long baseline (i.e., long spacing of jammer antennas) is an attractive option for cross-eye jammers, which can increase the angular error for monopulse radars. Phase error is a key factor restricting the performance of cross-eye jammers. In this paper, one of the sources of the phase error, i.e., local oscillator (LO) phase noise, is analyzed for a long-baseline cross-eye jammer. The effect of LO phase noise on the jamming performance is revealed for the first time. Additionally, the tolerance requirements for the LO phase noise of long-baseline cross-eye jammers are determined through theoretical analyses. Finally, the theoretical analyses are verified by Monte Carlo simulations. The research results can provide theoretical insights for system design and component selection for cross-eye jammers.
交叉干扰是一种用于欺骗单脉冲雷达角度测量的技术。长基线（即干扰器天线间距较长）是交叉干扰器的一个有吸引力的选择，它可以增加单脉冲雷达的角度误差。相位误差是限制交叉眼干扰器性能的一个关键因素。本文分析了长基线交叉眼干扰器的相位误差来源之一，即本地振荡器（LO）相位噪声。首次揭示了 LO 相位噪声对干扰性能的影响。此外，还通过理论分析确定了长基线交叉眼干扰器 LO 相位噪声的容差要求。最后，通过蒙特卡罗模拟验证了理论分析。研究成果可为交叉眼干扰器的系统设计和元件选择提供理论启示。
