Polarimetric Synthetic Aperture Radar Data and the Complex Wishart Distribution [PDF]
, 2003 When working with multi-look fully polarimetric synthetic aperture radar (SAR) data an appropriate way of representing the back-scattered signal consists of the so-callad covariance matrix. for each pixel this is a 3×3 Hermifian, positive definite matrix which follows a complex Wishart distribution.
