SAR Systems and Related Signal Processing

Synthetic Aperture Radar (SAR) is today a valuable source of remote sensing information. SAR is a side-looking imaging radar and operates from airborne and spacebome platforms. Coverage, resolution and image quality are strongly influenced by the platform. SAR processing can be performed on standard computers or dedicated hardware architectures, depending on required throughput and image quality. Besides imaging, SAR can perform other modes of operation and apphcations such as multi-frequency and polarimetric imaging, elevation mapping and moving target indication (MTI). Current developments in SAR systems are concentrated on higher resolution, and flexibility in performing advanced modes in the future
