为提升对机载多功能雷达对地探测模式的综合干扰效果,针对地对空雷达干扰中存在的雷达副瓣干扰效果差、合成孔径雷达(SAR)模式压制干扰难以及存在电磁暴露风险等难点问题,研究了针对机载多功能雷达不同工作模式的多站协同干扰部署方法,基于雷达干扰方程构建了针对实波束地图测绘(RBM)模式的雷达干扰装备部署计算模型,分析了对SAR模式不同压制干扰样式下的干扰功率计算方法,结合实例对多站协同干扰部署方法进行了仿真计算分析,仿真计算结果检验了干扰部署计算方法的有效性,该方法能够为电子防空作战中雷达干扰部署提供参考依据。

In order to improve the comprehensive jamming effect on airborne multifunctional radar of ground detection mode,and to address the difficulties of poor radar sidelobe jamming effect,difficulty in suppressing jamming on synthetic aperture radar(SAR) mode,and electromagnetic exposure risk in ground to air radar jamming,a multi-station cooperative jamming deployment method to different working modes of airborne multifunctional radar is studied.Based on the radar jamming equation,a radar jamming equipment deployment calculation model of real beam mapping(RBM) mode is constructed,and the jamming power calculation method for different suppression jamming styles to SAR mode is analyzed.The simulation calculation analysis of multi-station cooperative jamming deployment method is carried out combining with examples,and the simulation calculation results verifies the effectiveness of the jamming deployment calculation method.This method can provide reference basis for radar jamming deployment in electronic air defense operations.
