| 摘 要： | 作用距离是红外成像探测系统的主要技术指标之一,根据实际计算时部分参数可能未知的情况,推导了NETD表达的作用距离方程,并根据凝视型探测器的特点讨论了基于对比度的对高空目标作用距离的表达式,结合高空目标探测实验结果验证两种不同计算方法的有效性。分析结果对进一步的成像探测系统的设计提供了理论依据。

| Abstract: | Operating range is a core specification of an IR imaging detecting system. Since some parameters are unknown when calculating,deduce the operating range function with NETD. Then based on the characteristic of staring detector discuss the operating range for space targets based on contrast. Validate the validity of above two functions with experimental result. The analytical result provides the theoretical reference for design of imaging detecting system. |
