第三代红外搜索和跟踪（IRST）系统

红外搜索和跟踪系统是现代战争中重要的关键系统之一,随着军事的需要以及红外焦平面阵列的迅速发展,已经开始第三代红外搜索和跟踪系统的研究.第三代IRST系统的主要特点是探测和识别距离远,具有360°水平全景覆盖范围,单波段或双波段工作.本文主要介绍正在研制的几种典型的IRST系统,包括法国Thales的"月女神"IRST、法国Sagem的VAMPIR NG IRST、以色列Rafael的海上观察者等系统.未来的IRST系统将是多波段、多功能系统,能够实现全空域探测.文中还介绍了一些新的解决方案,如采用球形传感器和曲面焦平面,改善IRST系统的能力.

The third generation infrared search and track (IRST) system

Infrared search and track (IRST) system is one of most important crucial system in modern war. With the military requirements on IRST and fast developing of infrared focal plane arrays (IRFPA), the third generation IRST system has been developed. The 3rd Gen IRST systems are characteristic of long detection and identification, 360° panoramic view coverage and single or dual band operation. In the paper, typical IRST systems are introduced including ARTEMIS IRST system, VAMPIR NG IRST system and Sea Spotter IRST system etc. IRST system will operate in multiple band and will be multiple functional. Here some new solutions such as using spherical sensor configuration and curved FPA which can improve performance of IRST system are also described.
