초록

Airborne SARs are vulnerable to geometric distortion in squinted mode, and increased data distortion in forward-looking mode causes interpolation errors that degrade image quality. The polar format algorithm is preferred for convenient motion compensation and computational efficiency. This paper proposes a high-resolution SAR processing method based on sub-aperture division PFA: multiple antenna beams are steered over extended areas divided into sub-apertures, raw data are collected simultaneously, and the sub-images are processed in parallel to compensate phase distortion and merged into a complete SAR image over an extended area.
