Feasibility Study on Estimation of Sea Ice Drift from KOMPSAT-5 and COSMO-SkyMed SAR Images

Estimating the sea ice drift field is of importance in both scientific study and activities polar ocean. Ice motion being tracked at large scale (10 km larger) on a daily basis; however, higher resolution product desirable for more reliable monitoring rapid changes ice. The use wide-swath SAR has been extensively studied; yet, recent high-resolution X-band sensors have not tested enough. We examine feasibility KOMPSAT-5 COSMO-SkyMed retrieving by using dataset MOSAiC expedition. match-ups extracted from consecutive image pairs buoys than seven months central Arctic were used performance evaluation validation. In addition to individual tests COSMO-SkyMed, cross-sensor combination two was overcome drawback, relatively long revisit time SAR. experimental results show that accuracies are achievable single- configurations SARs compared C-band SARs, sub-daily feasible approach.
