摘要：

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