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.
