红外 (IR) 传感器和焦平面阵列 (FPA) 广泛应用于弹道导弹防御 (BMD) 中，用于监视、目标检测、目标跟踪和识别。这些功能是通过卫星、飞机平台、固定地点或拦截器执行的。大多数先进 BMD 目标的温度需要中波红外、长波红外或超长波红外波段的 FPA 波长。未来 BMD FPA 的重要 FPA 特性将包括大尺寸、高灵敏度、低 1/f 噪声：良好的均匀性和高可操作性。由于太空应用中的环境较冷，超长波红外对于传感器设计非常重要。具有低温、超长波高性能的红外传感器对于红外空间系统尤其重要。此外，多色红外传感对于消除大气层外辨别中地照的影响也很重要。本文将概述最先进的红外传感器，并讨论用于弹道导弹防御和天基应用的每种红外材料系统的优点和缺点。 (C) 2001 年由 Elsevier Science B.V. 出版
Infrared (IR) sensors and focal plane arrays (FPAs) are widely used in ballistic missile defense (BMD) for surveillance, target detection, target tracking, and discrimination. These functions are performed from satellites, aircraft platforms, fixed locations or interceptors. The temperatures of most advanced BMD targets require FPA wavelengths in the mid-wave IR, long-wave IR, or very-long-wave IR bands. Important FPA characteristics for future BMD FPAs will include large format, high sensitivity, low 1/f noise: good uniformity, and high operability. Due to the colder environment in space applications, very-long-wave IR is very important for sensor design. IR sensors with high performance at low temperature and very-long-wave is especially important for IR space systems. In addition, multicolor IR sensing is important to eliminate the effects of earthshine in exoatmospheric discrimination. In this paper, an overview of the state-of-the-art of IR sensors will be given, and the advantages and shortfalls of each IR material system for BMD and space-based applications will be discussed.
