This paper presents a study distilling radar backscatter measurements made by three Ku-band scatterometers of the Antarctic ice sheet over a nearly thirty-year study period. Backscatter signature modeling techniques are used to compensate for observation geometry and operating frequency differences among the sensors. Findings of this study include large regions of both positive and negative change in average backscatter, particularly in regions of West Antarctica and along much of the coast.
