Sensitivity of the radar signal to soil moisture: variation with incidence angle, frequency, and polarization

This study focuses on the variations of the radar sensitivity to soil moisture (dσ^o/dm_υ) with the radar configuration parameters (frequency, polarization, and angle). An analysis of variance shows that only the polarization significantly influences dσ^o/dm_υ, which is larger at cross-polarization than at like-polarized configurations
