双模导引头被动红外成像主动脉冲激光成像 Dual-mode seeker Passive IR imaging Active pulse laser imaging

摘要

针对巡航导弹以及各种对地攻击的灵巧炸弹的末制导段,提出了一种共孔径红外/脉冲激光(IR/Ladar)双模成像导引头系统设计方案,可用于对地面固定目标和各种可重定位(Relocatable)目标进行精确地识别和跟踪.该系统采用了被动红外和主动脉冲激光两种成像模式,以被动红外成像来辅助导引头对目标的搜索和捕获,以主动激光雷达成像来完成对目标的精确识别和跟踪,并且被动红外与主动激光成像系统共用一套光学系统,这样既满足目标搜索和捕获阶段的大探测视场的要求,又满足了目标识别跟踪阶段的高分辨率要求.

Abstract

According to the characteristics of the terminal guidance phase of cruising missile,the scheme of common aperture IR/Ladar dual-mode imaging seeker system is proposed.The seeker system can precisely track and recognize the stationary and relocatable object on the ground.The seeker design scheme includes two imaging modes,the passive IR imaging mode and active pulse laser imaging mode.The passive infrared imaging mode is used for the coarse object search and acquisition and the active pulse laser imaging mode is used for precise object recognition and tracking.At the same time,the two imaging mode use the common optics.So the seeker system can not only meet the requirements of the large field of view for object search and acquisition,but also meet the requirements of high resolution for object recognition and tracking.
