摘要
分析当对晴朗天空背景中的弱小目标进行探测的情况下红外成像系统的各种噪声源 ,给出各噪声源引入的噪声均方值与工作环境温度和背景红外辐射特性的定性关系 ,然后对图像空间噪声的靶场测量以及估计方法进行讨论。
When IR Imaging System detects small feeble target from fine air background ,the different noise sources of IR Imaging System were analyzed ,qualitative relationship of noise intensity and environment temperature and radiant intensity per unit area was elicited ,then prove ground measurement and estimate method of image spatial noise was discussed.
