摘要
ASAR是ENVISAT - 1搭载的最大遥感器 ,既是ERS - 1/2AMISAR的延续 ,又具有多模式、多极化、大幅宽、多入射角等特性。本文介绍了ASAR遥感器的独特优势 ,对ASAR各种工作模式和数据的特性、规格作了详细的说明。并简要地分析了ASAR数据在ENVIVIEW和ENVI等图像处理软件中显示的特点。最后 ,详细地分析了ASAR数据的应用潜力。
An advanced Synthetic Aperture Radar has been selected for the Envisat-1 payload ensuring continuity with ERS-1 and 2 AMI SAR and featuring large swath coverage, multiple choice of incidence angles, polarizations, modes of operation. In this paper, the ASAR instrument is described and the different modes of operation are presented. In addition, the kinds, characteristics and quality specifications of the ASAR data received and processed by China Remote Sensing Satellite Ground Station are presented in detail. This paper gives brief analysis about the features of the ASAR data showed in image processing software such as Enviview and Envi. Finally, potential applications of ASAR data are analyzed in detail.
