Özet
Circular synthetic aperture radar (CSAR) systems collect data over circular trajectories. Due to the curved, wide-angle geometry, focusing of CSAR data is known to be a difficult process. Additionally, when the spatial extent of the scene to be imaged is a significant fraction of the SAR path radius (i.e. in wide-field scenarios), layover phenomenon occurs which may further limit successful imaging of targets. In this paper, to characterize these layover effects, various simulation results for wide-field single-pass CSAR geometry are presented under point scattering assumption.
