Abstract

This paper presents a study that was conducted using ERS SAR archived images to assess the soil water-content of open desert areas containing two different soil types (loess and sand). For this purpose we used the different look directions model proposed by Blumberg and Freilikher. The results show that the soil moisture predictions are almost equal to those known as typical for these soil types at the equivalent seasons.
