摘　　要：对国外转塔式光电瞄准吊舱进行了划代,介绍了典型第三代吊舱的主要技术特点,定义了衡量光电吊舱集成度的四个评价标准:通光孔径与舱体直径之比、通光孔径的立方与系统重量之比,舱体直径的立方与系统重量之比以及有效载荷重量与系统重量之比,实现了从宏观层级对性能相近的光电瞄准吊舱功能密度或技术水平的定量评价。介绍了国外典型装备的发展状况,重点针对美国MTS-B吊舱、土耳其ASELFLIR350吊舱及之后的400/500、加拿大MX-15D吊舱、法国EUROFLIR410吊舱和德国ARGOS II HDT等典型产品进行了对比分析,介绍了各自的技术风格、特点和重要载荷;通过正向设计评估验证了MTS-B前置望远系统的性能指标和ASELFLIR350的光学有效载荷;总结了现代光电瞄准吊舱的几大趋同化技术特点:多波段共孔径折反式主系统+旁轴小口径次系统的光机架构正取得共识、多种波段的激光探测技术日益倾向主动光学方向、基于多轴多框平台和快反镜相结合的复合轴控制技术正在普及、详查探测更注重目标细节区域增强、多波段图像融合信息处理技术在显控中越发重要。The overseas turret-type electro optical(EO)targeting pods have been subdivided into different generations,therefore,the main technical characteristics of typical third-generation pods have been introduced.Four different evaluation criteria for measuring their integration degree have been defined:the ratio of the aperture of the optical aperture to the diameter of the turret,the cube of the aperture of the optical aperture to the weight of the system,the cube of the diameter of the pod to the weight of the system,and the ratio of the weight of the payload to the weight of the system,so as to achieve the quantitative evaluation of the functional density or technological level of the EO targeting pods of similar performances at the macroscopic level.The development status of typical equipment is introduced,focusing on the corporations of typical products such as the American MTS-B pod,Turkish ASELFLIR350 pod and the subsequent ASELFLIR400/500,Canadian MX-15D pod,French EUROFLIR410 pod and German ARGOS II HDT,etc.,and their respective technical styles,characteristics and core payloads are introduced.A forward design evaluation verifies the performance of MTS-B front telescope system and ASELFLIR350 turret's optical payload.Several assimilated technical features of modern EO targeting pods are summa rized:the optical-mechanical architecture of multi-band common aperture catadiopatric main system+side-axis small aperture sub-systems is gaining consensus;the laser detection technology of multiple wavelengths is increasingly inclined to the direction of active optics;composite-axis control technology based on the combination of multi-axis,multi-frame platforms and fast steering mirrors(FSM)is gaining popularity;the enhancement of target detail areas is acquiring more attention,and multi-band image fusion information processing technology is becoming more and more important.
