摘　　要：雷达遥感具有全天时、全天候的特点,在测绘中能够很好地弥补光学遥感的不足。随着SAR技术的不断发展,雷达影像得到了广泛的应用。然而受SAR相干侧视成像机制的影响,山区SAR影像的判读解译依然面临着巨大的挑战,制约着SAR在高山区测图、土地利用、地表覆盖等制图中的应用。本文以横断山脉地区为例,综合利用TerraSAR高分辨率升降轨影像,运用影像融合和镶嵌技术,结合实地调绘成果,对山区高分辨率星载SAR影像判读解译进行了深入研究,并最终形成了一套高效、可靠的解译流程。该判读解译流程对山区SAR影像在高山区测图、土地利用、土地覆盖制图中应用的推广具有重要的意义。Radar remote sensing is complementary to the optical remote sensing for its all weather and 24 hours round observation.Radar images are widely used in surveying and mapping with the development of technologies.However,for the influences of coherent and side looking imaging mechanism,it is very challenging to interpret SAR images in mountain areas,which restricts the applications of SAR images in land use/cover mapping.In this paper,a case of interpretation using multi-polarized high resolution satellite SAR images in mountain areas in Hengduan Mountains was studied by combining ascending and descending high resolution single polarized TerraSAR images using image fusion and mosaic.After comparing with in-site data,a set of efficient and reliable procedures for interpretation were generated,that is of great importance to broaden the use of SAR images in land cover/use mapping in mountain areas.
