凝视型红外搜索跟踪系统探测能力的分析

Analysis for detectability of staring IR search and tracking system

探测能力的强弱是广大凝视型红外搜索跟踪系统设计者和使用者一直关心的问题。对作用距离数学模型中影响探测能力的主要因素如目标、光学系统口径等进行了分析,还讨论了模型中未曾提到的一些因素,如路径辐射、光谱匹配等对探测能力影响的方式、程度。分析结果为增强凝视型红外搜索跟踪系统的探测能力提供了理论依据。

Designers and users always concern the detectability of an IR search and tracking system. The analysis for main factors such as target and aperture of an optical system, that affect detecting capability in mathematical model of operating distance is carried out. The affecting approach and degree for detectability of the system by some factors such as path radiation, spectral matching that do not mentioned in the model are also discussed. The analyzing results provide a theoretical basis for improving detectability of a staring IR search and tracking system.
