Abstract

Mid-wavelength infrared (MWIR) detection and long-wavelength infrared (LWIR) detection constitute the key technologies for space-based Earth observation and astronomical detection. The advanced ability of infrared (IR) detection technology to penetrate the atmosphere and identify the camouflaged targets makes it excellent for space-based remote sensing. Thus, such detectors play an essential role in detecting and tracking low-temperature and far-distance moving targets. However, due to the diverse scenarios in which space-based IR detection systems are built, the key parameters of IR technologies are subject to unique demands. We review the developments and features of MWIR and LWIR detectors with a particular focus on their applications in space-based detection. We conduct a comprehensive analysis of key performance indicators for IR detection systems, including the ground sampling distance (GSD), operation range, and noise equivalent temperature difference (NETD) among others, and their interconnections with IR detector parameters. Additionally, the influences of pixel distance, focal plane array size, and operation temperature of space-based IR remote sensing are evaluated. The development requirements and technical challenges of MWIR and LWIR detection systems are also identified to achieve high-quality space-based observation platforms.

中长波红外探测技术的发展和空间应用综述
中波红外(MWIR)探测和长波红外(LWIR)探测是天基地球观测和天文探测的关键技术。红外探测技术具有穿透大气层和识别伪装目标的先进能力,是天基遥感的绝佳技术。因此,这类探测器在探测和跟踪低温和远距离移动目标方面发挥着至关重要的作用。然而,由于天基红外探测系统的应用场景多种多样,因此对红外技术的关键参数有着独特的要求。我们回顾了中波红外和低波红外探测器的发展和特点,尤其关注它们在天基探测中的应用。我们全面分析了红外探测系统的关键性能指标,包括地面采样距离(GSD)、工作范围和噪声等效温差(NETD)等,以及它们与红外探测器参数之间的相互关系。此外,还评估了天基红外遥感的像素距离、焦平面阵列尺寸和工作温度的影响。还确定了中波红外和低波红外探测系统的开发要求和技术挑战,以实现高质量的天基观测平台。
