The dependencies of the backscattering from the ocean surface on the wind direction are analyzed by using the Pi-SAR under weaker wind condition (5m/s) than the former analysis under stronger wind as 14m/s.
In the X-band HH polarization, the dependency of the normalized cross section (NRCS) on wind direction depends on the incidence angle, differently from the former analysis. In the X-band VV polarization, the NRCS represents weak incidence angle dependency as same with the former analysis.
As a result, the dependency of the polarization ratio (PR) in the X-band on the wind direction also depends on the incidence angle. In the L-band, the dependencies of the NRCS and the PR are also weak, same as the former analysis. |
