舰用红外警戒系统在水面舰船上的作用越来越受到重视。基于线阵机械扫描的红外警戒系统由于受本身成像体制的限制，存在着一定的弱点。目前各国研制的第三代舰用红外警戒系统采用了多种新技术和新思路，对其进行分析和总结对新一代红外警戒系统的研制工作具有指导意义。

The shipboard infrared surveillance system is more and more important for the surface ships. But the infrared surveillance systems based on line array mechanical scanning are limited by the imaging system and have some disadvantage. At present, the 3rd generation shipboard infrared surveillance system adopts a lot of new technology and thought. The analysis and summarization of the system have guiding significance for our developing work.
