Abstract :
Since polarimetric SAR data are powerful tools to derive scattering mechanism of the observation target, it is expected to give us more detailed information in sea ice monitoring. Electro-Magnetic (EM) measurement for sea ice was conducted during the Soya cruise period in February, 2004. Pi-SAR/L-band polarimetric data simultaneously acquired during the ship cruise were compared with the sea ice thickness and the surface roughness derived by EM measurement. RR-LL coherence is related to sea ice surface roughness in lower incidence angle, while VV to HH backscattering ratio in higher incidence angle is also related to sea ice thickness.
