QUAD-POLARIMETRIC SAR FOR DETECTION AND CHARACTERIZATION OF ICEBERGS

摘要

This paper evaluates the performance of fully polarimetricrnSAR data in iceberg detection and characterization.rnThe study aims to explore the potential of RADARSAT-rn2 SAR data to detect icebergs and growlers in Svalbardrnthat have broken off from the glaciers nearby. To be ablernto detect iceberg/growlers in a SAR image, a significantrncontrast between iceberg and background clutter is required.rnThe sublook cross-correlation magnitude (SCM)rnis extracted from the complex cross-correlation betweenrnsubapeture images and contrast between iceberg and searnclutter is measured. The results of target-to-clutter ratiornfrom the SCM indicate that the sublook analysis has anrnimpact on detection performance.
