A quasi-geostationary SAR: Benefits and challanges

Quasi geosynchronous SARs are unique in their continuous imaging capabilities, providing new applications and enhancing the existing ones. However, the large integration time, minutes to hours, introduce clutter noise due to atmospheric turbulence, moving targets, and other minor effects like platform vibration or clock jitter. A proper modelling of these effects provide a qualitative and quantitative evaluation of the errors, and can be used to simulate geo-SAR focused images.
