| 摘 要： | 因ASAR（Advanced Synthetic Aperture Radar）具有全天候、全天时、穿透性强、多种入射角、宽幅成像、多模式、多极化等优势,而成为遥感研究和应用的热点。它是当今最先进的合成孔径雷达数据。本文对ENVISAT的ASAR数据类型进行介绍,并利用欧空局开发的雷达处理工具NEST（Next ESA SAR Toolbox）软件包和ENVI软件对雷达数据进行辐射定标、影像校正和图像滤波处理,为ASAR数据处理方法提供了有益补充。

| Abstract: | ASAR（Advanced Synthetic Aperture Radar） has become a hot study field of remote sensing because of its unique advantages,such as all-weather,multiple choices of incidence angles,large swath coverage,multiple modes of operation and polarizations,which is the most advanced synthetic aperture radar at present.In this paper,ENVISAT-ASAR data types are introduced,and radiometric calibration,image correction and image filter are processed by ENVI and NEST（Next ESA SAR Toolbox） that is a free software to process ASAR data developed by European Space Agency.It can provide useful supplement for ASAR data processing. |
