Abstract:

High spatial resolution Synthetic Aperture Radar（SAR） satellites (1 m/3 m) have been launched recently which provided more choice to carry out land remote sensing project. In order to evaluate its suitability, there high resolution SAR satellites were selected for evaluation including TERRASAR, COSMO SkyMed and RADARSAT-2. Comparative analysis and statistical evaluation were used. The result shows that TERRASAR, COSMO SkyMed, RADARSAT-2 had similar ability for land use discrimination and land use dynamic change detect. Spotline mode data had relative high accuracy which obtains 80% overall acuracy for land use thematic mapping while stripmap mode data only obtained less than 75% overall accuracy for the same test sites. The result showed that evaluated SAR data can be used in land use dynamic monitor project.
