Resolution Equation for SAR Systems Synthesizing Circular Aperture
IEEE AccessThe resolution of a synthetic aperture radar (SAR) system depends not only on the operating frequency range of a radar but also on the geometry. A radar system operating at MHz frequencies facilitates SAR resolution to the meter (m) level with a linear ...

A Focusing Algorithm for Circular SAR Based on Phase Error Estimation in Image Domain
Leida xuebao, 2015 Residual motion error is common in high-resolution circular Synthetic Aperture Radar (SAR) image defocusing. The Signal-to-Clutter Ratio (SCR) in echo data domain is relatively low; thus, the phase error spans several range bins.
