Abstract:
Simulations of SAR images obtained from a Geosynchronous Synthetic Aperture Radar (GEOSAR) is performed. Different errors on the orbit used for the image SAR processor are introduced to show quantitative information about the loss on range and azimuth resolution. Some simulations for correcting the errors using autofocus are explained.
