Abstract

The potential of synthetic aperture radar (SAR) data for monitoring roughness states over bare agricultural fields has been investigated using one ERS image (23°) and two RADARSAT images (39° and 47°). At a high incidence angle (47°), the influence of soil roughness on radar return predominates over the influence of other soil parameters, making it possible to discriminate and map various surface roughness classes over agricultural fields
