Urban change detection by comparing SAR images at different resolutions and polarimetric modes

Today, the variety of remote sensing satellites increases the interest of combining images of different types to satisfy the needs of earth monitoring with a better reactivity. In this context, this article aims to demonstrate the feasibility of change detection between a high resolution SAR image and a polarimetric SAR image. It highlights the interest of this configuration for change detection but also the analysis of these change areas through to the polarimetric information. The approach is applied to the case of urban areas.
