主 题：remote sensing synthetic aperture radar applications
摘 要：The first pictures of the earth were taken from a balloon in the mid-19^(th) century and thus started‘earth observation’.Aerial missions in the 20^(th) century enabled the build-up of outstanding photographic libraries and then with Landsat-1,the first civilian satellite launched in 1972,digital images of the earth became an operational *** main roles of earth observation have become scientific,economic and strategic,and the role of synthetic aperture radar(SAR)is significant in this overall *** image exploitation has matured and several operational programs regularly use SAR data for input and numerous applications are being further *** technological development of interferometry and polarimetry has helped further develop these radar based *** paper highlights this role through a description of actual applications and projects,and concludes with a discussion of some challenges for which SAR systems may provide significant assistance.
