Ground-based SAR imaging basics and land clutter effects on the focused image

Abstract

Remote Sensing is the science and art of obtaining information about an object, area, or phenomenon through the analysis of data acquired by a device that is not in contact with the object, area, or phenomenon under investigation. SAR is a form of radar whose defining characteristic is the use of the relative motion between its antenna and the target region. The basic principles of radar imaging are recalled and the effects of some specific land clutter (such as windblown radar ground clutter) in SAR focused images are analyzed. Finally, a brief description of the UPC X Band SAR system architecture is presented.
