点源目标的红外成像系统作用距离分析

Theoretical Analysis of the Operating Range of Infrared Imaging System

红外系统的作用距离是红外探测系统的一个重要的综合性能参数,它直接影响红外图像的像质,从而影响目标的提取与识别。基于NETD和NEFD对红外成像系统的作用距离进行了详细的分析,以便在设计中参考使用。

The operating range of infrared system is a very important parameter of the system of the infrared detection. It affects the quality of the infrared image . Thereby it affects the result of the detection and recognizing of infrared target. So the NETD and NEFD to estimate the operation range are useg.
