摘　　要：针对海空复杂背景下红外小目标识别的需要,对海空背景及其弱小目标的红外图像特性进行了统计分析。根据图像特性的差异,可以判断图像中是否存在目标,从而为目标识别提供了关于目标识别和背景的先验知识,研究结果可用于海空背景下小目标的检测。A statistical analysis of features of infrared images of small targets and backgrounds is made according to the practical requirement for small target recognition under the complicated background of sea and sky.Based on the difference of image characteristics,it can be determined whether the target exists.This research provides the researches with prior knowledge about small target and background on target recognition.The results can be applied to the IR detection of small targets in sea and sky background.
