SAR image formation and exploitation using high resolution radar data

Synthetic Aperture Radar (SAR) images can be used in various applications such as Digital Elevation Model (DEM) generation, ground deformation monitoring, and detection of natural and man-made fine scale changes. After scanning the imaged scene, focusing algorithm is applied on raw radar data to obtain exploitable SAR images. With the availability of high resolution radar images, there is a real opportunity for studying the new applications of the SAR images. It is in this context that the present work was developed with a main objective of providing a further analysis of Range Doppler focusing algorithm. We are also interested by the use of the obtained SAR images in the application of change detection based on coherence estimation.
