| Abstract: | The basic principle and the products of GLAS are introduced in the paper. The contained errors and corresponding correct model are analyzed. And the algorithm about waveform processing applied for different kinds of surface character such as ice sheet, sea ice, land and ocean is also studied. And algorithm about obtaining the parameters of surface character, such as surface slope, is included. Meanwhile the algorithm for the determination of geolocation of the footprint is also studied. |
