摘要：紅外搜索與跟蹤系統(tǒng)被廣泛應(yīng)用于現(xiàn)代國防中針對遠(yuǎn)距離目標(biāo)的檢測、跟蹤及預(yù)警。但是，該統(tǒng)檢測的目標(biāo)一般為尺寸較小且模糊的點(diǎn)狀結(jié)構(gòu)通常難以辨別，一種基于圖像中目標(biāo)與背景局部結(jié)構(gòu)的差異性，采用NRAM模型實(shí)現(xiàn)的方法可以對單幀紅外圖像中的小目標(biāo)進(jìn)行有效檢測。

Abstract： Infrared search and tracking system is widely used in modern national defense for long-range target detection， tracking and early warning. However， the target detected by the system is generally a small and blurred dot structure， which is usually difficult to identify. A method based on the difference between the local structure of the target and the background in the image，which is implemented by the NRAM model， can effectively detect small targets in a single frame infrared image.

Key words： infrared small target detection; NRAM model; sparsity; low-rank
