摘要
简要地分析了ＨＲＩＳ数据中噪声的频谱特征，并在此基础上提出了一种基于噪声频谱特征的自适应维纳滤波迭代处理方法，实验表明该噪声处理方法具有很强的自适应和噪声抑制能力，完全满足实际的需要。
This paper analyzes the spectrum characteristic of the noise in HRIS, and presents an adaptive Wiener filtering iterative processing method. Experiments proved that the method has an adaptive ability and a noise restraining ability, which meets the practical needs.
