【Abstract】 As a new technology, microwave scatterometer has been applied in many fields. This paper briefly represents its principle and development of satellite scatterometers, also a algorithm called SIRF(Scatterometer Image Reconstruction with Filter) used to improve the resolution of scatterometer image. Several types of microwave scatterometer are introduced. On the basis of it, the application in the ice sheet and sea ice of polar regions, e.g. sea ice extent mapping, sea ice motion monitoring, sea ice classification and ice sheet onset thaw is described briefly.更多还原
