Abstract:
Radar ice sounding allows for the retrieval of ice depth and provides information on ice structures, flow, and layering. In the perspective of a future spaceborne ice sounding mission, surface clutter cancellation is a crucial aspect for extracting subsurface radar echoes. ESA’s P-band POLarimetric Airborne Radar Ice Sounder (POLARIS) enables simultaneous reception of up to 4 sub-apertures channels. Different surface clutter suppression techniques are presented, analysed and compared. Applicability and clutter rejection performance of the techniques is then demonstrated on a multi-channel dataset of the 2011 POLARIS Antarctica campaign.
