Effect of Cross-eye Jamming on the Active-passive Composite Monopulse Radar

交叉眼技术是一种通过相干多点辐射源诱使单脉冲雷达测角偏差的电子对抗技术。面对攻防双方激烈对抗的复杂电磁环境,采用主被动复合单脉冲雷达测角是现代末制导雷达提高抗干扰能力的发展趋势之一。该文以主被动复合单脉冲雷达为干扰对象,建立了交叉眼干扰数学模型,通过对比交叉眼技术对抗主动单脉冲测角和被动单脉冲测角的干扰效果,揭示了交叉眼技术对主被动复合单脉冲雷达的影响机理。该研究成果可为干扰与抗干扰的合理应用提供理论规律和仿真数据。

Cross-eye jamming is an electronic countermeasure technology used to cause angular deviation of monopulse radar via multiple coherent sources.Despite a complex electromagnetic environment,using activepassive composite monopulse radar is a development trend for improving the anti-interference ability of modern terminal guidance radar.A mathematical model of cross-eye jamming considering the active-passive composite monopulse radar is established.The influence mechanism of cross-eye jamming on the active-passive composite monopulse radar is revealed by comparing the effect of active and passive monopulse radar systems on angle measurement.Furthermore,the results can provide theoretical guidance and simulation data to reasonably apply Electronic Countermeasures(ECMs)and Electronic Counter-Countermeasures(ECCMs).
