Both single-polarized [8], [10], [14] and dual-polarized (HH
and HV) [11]–[13] SAR images have been used to extract ice
and water features. HH and HV pol complement each other.
HH-pol images contain more details but are strongly affected by
incidence angle. HV-pol images contain different information
of the ice and are visually less affected by incidence angle.
