基于主被动复合导引头的干扰态势构建

Jamming Situation Construction Technology Based on Active⁃Passive Composite Seeker

在导引头主被动信息融合过程中,存在多装备与多目标平台关联困难、无法有效提取目标特征信息,难以有效融合构建态势的问题。因此,本文提出一种将导引头主动雷达信息和被动侦察信息融合的数据关联方法。该方法先提取导引头干扰态势表征要素,然后以目标方位为中心,将平台与装备关联,构建干扰态势。本文通过主被动信息融合构建的态势,在原先分离的平台和设备间建立空间位置与搭载的关系,可以有效地消除欺骗式干扰和多径散射假目标,提高态势认知效率。

In the process of active and passive information fusion of radar seeker,there are problems that it is difficult to associate multi⁃equipment with multi⁃target platform,unable to effectively extract target feature information,and difficult to effectively integrate and construct a situation.Therefore,this paper proposes a data correlation method that integrates seeker active radar information and passive reconnaissance information.In this method,the interference situation characterization elements of the seeker are first extracted,and then the platform⁃equipment association is made by the target azimuth to construct the interference situation.In this paper,the situation constructed by the fusion of active and passive information can establish the spatial position and carrying relationship of the separated platform and equipment,which can effectively eliminate deceptive interference and multipath scattering false targets,and improve the situation cognitive efficiency.
