摘要 分析了永久散射体PS（Permanent Scatlerers）处理中进行大气改正的必要性，介绍了大气改正的方法，指出现有方法存在
的不足； 结合利用MERIS数据进行大气改正的优势，提出了基于MERIS数据的PS处理中大气改正的模型。采用青藏高原北麓河实验区
ASAR数据对该模型进行验证的结果表明，该方法能够有效提高永久散射体处理中大气改正的可信性，从而使得利用相对较少的ASAR数
据进行PS分析成为可能。

Abstract ：This paper has analyzed the importance of atmosphere correction in PS processing, described the existent
method for atmosphere correction, and pointed out the shortcoming in the existent method for atmosphere correction
in PS processing. Considering the advantages of correcting atmosphere effects based on MERIS, this paper presents a
method for atmosphere correction combined with MERIS in PS processing. For the purpose of evaluating the methods for
atmosphere correction, the authors conducted an experiment to compute the atmosphere effect with the presented
method by using ASAR data covering Beiluhe test area. The result indicates that, with this method, the atmosphere
correction can be made in PS processing with relative fewer SAR data.
