Objectives: The SAR images are highly noisy so a technique is applied that can de-noise the input image for batter analysis of the features. Methods: RADARSAT1 imagery data is utilized by Synthetic Aperture Radar to detect the ice at different regions of the seas. Automated algorithm gives better consequence of target utilizing R1 imagery data. To de-noise the input satellite images, gobar filter is applied. The gobar filter is the patch based filter in which patches are created of the whole image and patch which has dissimilar properties are removed from the image. Finding: The proposed and existing algorithms are implemented in MATLAB by considering the SAR dataset. It is analyzed that after de-noising the image, properties of the image like thickness, concentration and velocity is analyzed efficiently. The results of the image such as ice thickness, ice velocity and ice concentration is increased up to 10 %, 12 % and 18 %, respectively.
