摘　　要：为一种被动式告警系统,舰载红外搜索与跟踪系统(IRST)能够可探测和跟踪掠海反舰导弹和低空威胁目标,为舰船作战管理系统和指挥控制系统提供目标指示信息,在提高舰船的态势告警能力和自防御能力方面具有不可替代的优势。与传统的360°机械扫描的IRST系统相比较,新型的凝视型IRST系统使用多个基于FPA阵列凝视非转动传感器组件,增大俯仰角覆盖,具有的高数据更新率确保快速反应时间,增强了对高速低探测性目标以及非对称威胁目标的自动探测和跟踪性能。论文介绍国外新型凝视型舰载红外搜索与跟踪系统的发展现状、技术特点和应用,对重点技术进行了分析。As a passive warning system,shipborne infrared search and track(IRST)system has the capability to detect sea-skimming anti-ship missiles and low-altitude air threats,and provide target designation for ship combat management and command and control system,therefore it has remarkable advantages in terms of improved situation awareness and self-defense for surface ships.Compared with traditional IRST system based on 360°mechanical scanning,new generation staring IRST uses FPA-based starring non-rotational sensor to extend the elevation coverage,obtain high data refresh rate to ensure quick reaction to threats and enhance the automatic detection and tracking capability against high-speed,low-detectability or asymmetric threats.In this paper,the development status,technical characteristics and application of new generation shipborne staring infrared search and track system abroad are presented,and analysis of its critical technologies are given as well.
