Experiments have been also carried out using HV pol or HH
pol only (results not shown here). The use of dual-pol SAR
image is able to produce a better ice concentration estimation
than using HH or HV only, as has been demonstrated in previous
research [12], [34]. When using HH pol only, the results
are strongly affected by the incidence angle, whereas using
only HV pol shows banding in the resulting ice concentration
estimate.
