摘 要:
在采用喷射式制冷体制的红外线列探测器扫描成像系统中，探测器焦面温度是时变的，使现有的非均匀性校正方法无法抑制空域噪声，难以进行目标检测识别。根据扫描成像特点，提出一种在高空域噪声存在的背景中进行目标检测识别的解决方案，利用多通道并行处理、决策级融合方法，避开空域噪声的影响，实现了目标的检测识别。[著者文摘]

Abstract:
The temperature of the FPA changes with time in the IR scan imaging system using the direct-spray cooler. Existing NUC method （for example,Two-point NUC） can＇t restrain the spatial noise and the detection and recognition of target can＇ technique of target detection and recognition in multi-channel processing method and fusion on t be done . Based on the character of Scan Imaging,a the background with severe spatial noise is given. Using decision level to avoid the influence of spatial noise , target detection and recognition is realized.[著者文摘]
