 A study was conducted using radar set, two images and field measurements to evaluate the potential of polarimetric observations for crop monitoring, specifically backscattering ratios, normalized correlation between HH and VV, and dominant alpha angle, which showed significant correlations with biophysical variables such as biomass, height, or leaf area index at incidence angles of 31 degrees or 36 degrees. The joint use of data acquired with different beams could increase the refresh rate of information about crop condition. This article was authored by Ruben Valkastoneo, Juan M.
