  • Abstract
    We propose a novel technique to estimate the Azimuth Antenna Pattern (AAP) from SAR images. The technique first perform azimuth focusing at enhanced resolution, then selects those scatterers that are less affected by ambiguous returns and finally derive the AAP by spectral analysis. Results achieved by processing ENVISAT-ASAR data are presented.
