摘要
文中介绍了国外制导用激光成像雷达近年来的发展情况 ,总结提出了激光主动成像制导雷达的研究方向。CO2 激光成像雷达系统效率高 ,大气传输性能好 ,信息处理技术成熟 ,易于实现高灵敏度外差探测和三维成像 ,曾经是主要的研究对象 ;固体激光雷达系统具有系统质量轻、价格低 ,探测器不需要制冷的独特优点正成为现在研究热点 ;二极管激光成像雷达体积小、造价低、寿命长、可靠性高、功耗低 ,可采用室温探测 ,有着很大的发展前途。
In this paper, the latest development of imaging guiding lidar overseas is introduced, and the future of that is predicted. The CO\-2 lidar system has the advantages of higher efficiency, better transmission capability in air, more developed information processing technology, easy to actualize the coherent detection with high sensitivity, and 3D imaging, so it has been the main object for studying. For the special excellence of light weight, lower price, and detector without cooling, the solid imaging lidar system is now being a hot spot of research. With well outlook, the diode lidar system has got more characteristics than the systems before.
