电子对抗侦察卫星对警戒雷达侦察效能分析

Effectiveness Analysis of Search and Warning Radar Reconnaissance byElectronic Countermeasure Reconnaissance Satellite

电子对抗侦察卫星对海上搜索警戒雷达的电磁信号侦察有其独特优势,以往的研究更多的是侧重于卫星的重访周期、覆盖范围等方面,缺少卫星对信号侦察能力的定量分析。通过分析舰船雷达信号在空间的功率密度分布,构建了电子对抗侦察卫星对海上搜索警戒雷达的侦察模型,将三型典型海上搜索警戒雷达的相关数据带入模型进行了仿真,并分析了持续侦察时间,最后提出了下一步的研究建议。

The electronic countermeasure reconnaissance satellite has its unique advantages in the electronic signal reconnaissance of the search and warning radar.Previous studies have focused more on the revisit period and coverage of satellite,lack of quantitative analysis of satellite signal reconnaissance capability.By analizing the power density distribution of ship radar signal in space,the reconnaissance model of ECM reconnaissance satellite for search and warning radar on sea is constructed.The data of three typical radars are brought into the model and simulated,and durations of reconnaissance are analyzed.Finally,some suggestions for further are put forward.
