Polar sea ice classification using enhanced resolution NSCAT data
Abstract- The NASA scatterometer (NSCAT) collected Ku-band scatterometer measurements from Sept. 1996 to June 1997. These data are converted high resolution six day images of the polar regions through the use of the scatterometer image reconstruction with filter (SIRF) algorithm. SIRF produces image...

A simple four-dimensional classification technique is proposed which uses the dual polarization parameters A,, Ah, B,, and Bh. A k-means clustering classification can be used to separate pixels of the images with differing scattering mechanisms. This method also adapts to the seasonal characteristics of cluster migration by converging to the locally optimal cluster centroids.
