Abstract
An algorithm to process the synthetic aperture radar (SAR) data in wavenumber domain, is discussed. Generated from the seismic migration technique in the area of geophysics, this imaging method has been modified and developed in the area of SAR imaging. The basic idea of original seismic migration technique is analysed and modified to suit the feature of spaceborne SAR imaging. The result shows that the new algorithm will improve the image quality without additional computational time because the correction can be realized by phase shifting and fusion to pulse compression in the azimuth direction.
