利用高轨预警卫星提升远程预警雷达预警能力研究

摘要
以典型的洲际弹道导弹为研究对象,首先分析了基于协方差分析描述函数(CADET)的弹道误差传播过程,利用误差协方差矩阵产生预警信息,进而研究了预警信息向雷达工作所需的引导信息的转换过程。最后,分析了相控阵雷达在引导信息有无情况下不同的工作方式,量化分析了引导信息对雷达工作效果的提升。建立了典型反导场景并进行仿真,结果显示预警引导信息的存在将有效减小远程预警雷达的搜索空域,提升雷达探测距离,缩短目标发现时间。
Taking the typical intercontinental ballistic missile as the research object,the ballistic error propagation process based on the covariance analysis description function( CADET) was analyzed firstly.The error covariance matrix was used to generate the early warning information. Furthermore,the conversion process of warning information to guidance information which was required for the radar work was studied. Finally,the different working modes of phased array radar in the presence or absence of guidance information were analyzed,and the improvement of the working effect of guiding information on radar was quantitatively analyzed. The simulation results show that the existence of early warning guidance information will effectively reduce the search space of long-range early warning radar,improve radar detection distance and shorten target detection time.
