The purpose of the paper is to estimate the Azimuth Antenna Pattern by using Persistent Point Scatterers (PPS) selected in a stack of interferometric Synthetic Aperture Radar images. Wide angle antenna pattern is estimated from targets spectra by means of a Maximum Likelihood formulation. PPS are considered a restricted subset of the Persistent Scatterers, for which the point-shape feature is further required. A model for PPS is provided and experimentally validated; antenna estimation results are presented for both simulated and real X-band Cosmo Skymed data

Abstract
The purpose of the paper is to estimate the Azimuth Antenna Pattern by using Persistent Point Scatterers (PPS) selected in a stack of interferometric Synthetic Aperture Radar images. Wide angle antenna pattern is estimated from targets spectra by means of a Maximum Likelihood formulation. PPS are considered a restricted subset of the Persistent Scatterers, for which the point-shape feature is further required. A model for PPS is provided and experimentally validated; antenna estimation results are presented for both simulated and real X-band Cosmo Skymed dataFile in questo prodotto:
