X波段PD雷达杂波抑制性能分析

Performance Analysis of Clutter Suppression for X-Band PD System Radar

对于X波段地面雷达,要使其在云雨等动杂波环境下的目标检测能力达到指标要求,杂波抑制性能改善非常重要。采用PD技术的地面雷达对此至今尚无明确的论述。基于某型该波段雷达不同PRF时信杂比改善因子的比较分析,对地面雷达采用PD技术时的杂波抑制性能进行了分析,最终的信号仿真论证也证实了分析结果的正确性。

For X - band ground - based radar, in order to reach the target detection ability require- ment in cloud and rain clutter, the performance improvement of clutter suppression is very important. However, there are no relevant demonstrations in ground-based radar using pulse Doppler （PD） system. Based on the comparative analysis of signal noise ratio （SNR） improvement factor for some type X-band radar, the performance improvement of clutter suppression of ground-based radar using PD system is ana- lyzed, the final signal simulation demonstration confirms the correctness of the analysis.
