    An-assessment-of-ERS-SAR-Low-Resolution-Imagery.pdf

    The objective of this technical note is to describe and to analyse the various concepts associated with the ERS SAR low resolution imagery. This study is done in order to evaluate a range of products, to consider the trade-offs involved in product specification and to propose some recommendations fro low resolution imagery of quality suitable for a broad range of potential applications.
