The size of filtering window has obvious impact on the effect of SAR image filtering. Different sizes of filtering windows, from 3×3, 5×5, 7×7, to 9×9 (pixel×pixel), were used in some useful filtering methods such as Kuan algorithm, Frost and Enhanced Frost algorithm, Lee and Enhanced Lee algorithm. Several cases of filtering performance were compared and studied based on different indexes. It is shown that the filtering window with 5 pixel ×5 pixel can yield better performance.
