摘　　要：机载飞行视景系统综合数字地图数据、雷达数据、光电数据与导航数据进行数据融合生成机舱外视景画面,能够辅助飞行员在降级视觉环境下执行等效目视飞行。机载飞行视景技术为飞行员提供实时感知辅助与行为引导,提升飞行员情景意识,增强飞行安全。基于飞行视景技术开发出了合成/增强/综合视景系统、地形感知与告警系统、贴地飞行辅助系统等。这些系统不仅能够增强飞行安全,更进一步提升飞机全天候的任务能力。介绍了机载飞行视景技术的基本原理,回顾了四十余年的发展历程,指出存在的问题和可能的解决方法,展望了未来机载飞行视景技术的重点研究方向。Airborne flight vision system carries out multisource data fusion during flight.It comprehensively processed and integrated digital map,radar,optical video and navigation data to output conformal and equivalent out of cabin view.Airborne flight vision system assists pilots in perception and guidance,which enhance pilots′situation awareness and flight safety.The synthetic/enhanced/combined vision,terrain awareness and warning system,nap of the earth assistant system are all based on flight vision technology.These systems not only improve the flight safety but also promote the all weather mission capabilities.In the article,we firstly introduce the basic rationale of flight vision system and then review the 40 years research and develop history of airborne flight vision system.Furthermore we point out few key problems and possible solutions in this area.Finally we make expectations for the future study research trends in flight vision technology.
