HIGH RESOLUTION AIRBORNE SAR IMAGE CHANGE DETECTION IN URBAN AREAS WITH SLIGHTLY DIFFERENT ACQUISITION GEOMETRIES
Change Detection SAR Remote Sensing Imaging Geometry Feature Building
2015/4/1
Before applying change detection, high resolution SAR (Synthetic Aperture Radar) imagery benefits from advanced denoising mechanisms to preserve details and minimize speckle. We propose a change detec...
UTILIZATION OF LIDAR DEM FOR SAR IMAGE ANALYSIS IN DENSE URBAN AREAS
SAR LIDAR Distortion Simulation, Fusion
2015/3/25
The increasing resolution of SAR data opens the possibility to utilise this data for scene interpretation in urban areas. Different SAR
