Backscattering characteristics of ice on Lake Saroma observed by PALSAR-2 and Pi-SAR-2L

摘要

The main objective of this research is to investigate the possible use of L-band SAR data to monitor sea ice in relatively thin sea ice area. By taking profiles of polarimetric parameters along a line crossing from west to east edges of Lake Saroma, the polarimetric and the incidence angle characteristics for various ice types were extracted. It was found that VV to HH backscattering ratio at higher incidence angle was correlated with ice thickness. Calm open water had relatively high scattering entropy due to low backscattering coefficient close to noise equivalent backscattering coefficient.
