Breaking the isotropic scattering assumption in wide-beam stripmap SAR imaging

摘要

This paper considers stripmap SAR imaging using a wide-beam antenna. In this case, anisotropic scattering is observed from objects that are illuminated from a wide range of aspect angles. Traditional imaging algorithms assume isotropic scattering. This paper investigates the use of constrained optimization for jointly estimating a sequence of images that correctly account for aspect dependent scattering.
