Abstract： This report presented the annual research progress of the 863 project in 2013， in the context of construction of an airborne polarimetric interferometric SAR （PolInSAR） system， comprehensive campaign of high-resolution SAR and development of demonstration application software of high-resolution SAR， and etc.. In the aspect of airborne PolInSAR system construction， we have accomplished the construction of the X-band PolInSAR sensor， the SAR systems laboratory joint debug test， and the aircraft flight calibration experiments. We have implemented the comprehensive experiment for high-resolution SAR in the test site of Ruoergai County of Sichuan Province and successively in the test site of Genhe of Daxing'anling in Inner Mongolia. Totally， about 28.5 TB of airborne X-band double antenna InSAR and P-band polarimetric SAR data， covering 8 619.8 km2 campaign area， was acquired. The preprocessing for all the SAR data has been finished. Moreover， the multi-temporal Radarsat-2 quad-polarization SAR and Landsat-8 multi-spectral satellite data covering the Genhe experimental area was obtained. At the meanwhile， the comprehensive and real-time or nearly real-time ground investigations were organized， and from 8 institutes and universities under the framework of the project， the teams of 50 person-times were involved. The ground truth data， such as the forest leaf area index （LAI）， farmland vegetation parameters， soil and meteorological parameters and land cover types were measured. For the development of high-resolution SAR application software， the prototype of software modules has been completed， including topographic mapping， land use and vegetation type classification， forest vegetation vertical structure parameter estimation， and etc. Improvements for these modules and their integration to the whole software system are ongoing using the uniform development language and standard under the frame of the projects system software in order to develop one high resolution SAR application software with user-friendly interface. As we expected， the achievements of this year will support the application and demonstration of high resolution SAR， which is our future work in the next year 2014.
