摘要
简要介绍了微波散射计的原理、星载微波散射计的发展状况及用于提高散射计图像空间分辨率的图像滤波重建算法。在此基础上结合几种星载微波散射计数据简要介绍了微波散射计在南北两极的应用情况 (海冰图测绘、海冰运动监测、海冰分类、极地冰盖研究等 )及其未来研究展望。
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.
