METHOD AND DEVICE FOR IMPROVING QUALITY OF SCANSAR IMAGE

摘要

Disclosed is a method for improving quality of a ScanSAR image, and the method includes that range compression and RCMC are performed on each sub-swath of ScanSAR data; sub-aperture segmentation is performed on the ScanSAR data subjected to the range compression and the RCMC; aperture interpolation is performed on each sub-aperture data; and azimuth compression is performed on the sub-aperture data subjected to the aperture interpolation. Further disclosed is a device for improving quality of an ScanSAR image.
