| In this study, data acquired by the Canada Centre for Remote Sensing ground-based scatterometer were used to evaluate how radar backscatter varied as a function of frequency, polarization and incidence angle, soil moisture and plant moisture for fallow, wheat and canola targets. Specifically, the radar data were collected at 1.5 GHz (L-Band), horizontal polarization, 5.3 GHz (C-Band) vertical polarization and C-Band horizontal polarization at incidence angles of 20;In general, the linear models indicated that radar correlation to soil moisture decreases and correlation with plant moisture increases with increasing incidence angle and as frequency was increased from L-Band to C-band. (Abstract shortened by UMI.).;Linear correlation coefficients were computed between the radar backscattering coefficient and soil moisture. Similarly, the correlation coefficients were calculated between the radar parameters and plant moisture for the wheat and canola targets and between each set of radar parameters and soil moisture and plant moisture for all targets combined. |
