Radar remote sensing provided significant results in the and and semi-arid regions. The backscatteriing coefficient is very sensitive to the roughness of the soil and reg surfaces. In the particular case of the Tunisian Chotts, this relatively simple sketch is complicated by the presence of saline pan and mudflats, and large temporary water surfaces, the,so-called playa lakes, depending upon pluviometry. A. preliminary approach using three SAR frequencies allowed us to standardize the analysis for a more elaborated work in progress.
