针对火箭测控链多台同频雷达合作跟踪同一个箭上目标时产生的同频干扰,文中从雷达特殊时序、火箭残骸信号等 因素对前卫门的影响着手,深入分析了前卫门机制的缺陷,设计通过适当调整雷达发射信号的特征,改善雷达分辨非相参 干扰信号的能力,进而彻底消除现行单脉冲雷达在应答式跟踪时产生卫门盲区的问题,以及同频干扰带来的影响,为下一 步雷达设计提供参考。

Aiming to the same frequency jamming caused by several radars tracking a single target, and based on impact of sanforized timing sequence in single-pulse radar and debris signal, et al. The bug of the existed mechanism for eliminating same frequency jamming is analysed. In addition, radar's ability of distinguishing interfering signal is improved through the appropriate adjustments radar signal characteristics and then the bug of the guard door on response type tracking and the impact of frequency jamming are eliminated. At last, it is hoped for providing reference for radar design.
