摘要: The RADARSAT Geophysical Processor System (RGPS) is a data processing system for the analysis of synthetic aperture radar (SAR) sea ice acquired by Canadian satellite (Raney et al. 1991). was launched in November 1995 into 24-day repeat cycle, an orbit configuration which provides near coverage high latitudes at 3- and 7-day intervals. SAR sensor has number imaging modes, one illuminates wide swath (460 km) designed large scale mapping Earth’s surface. science plan Alaska Facility calls weekly Arctic Ocean. With this mode, Ocean every 7 days (Fig. 1) with 100 m pixels produces approximately 1 GB image daily. In effort to make volume more useful scien-
