Bias Correction and Modified Profile Likelihood under the Wishart Complex Distribution

open access: yes, 2014
This paper proposes improved methods for the maximum likelihood (ML) estimation of the equivalent number of looks $L$. This parameter has a meaningful interpretation in the context of polarimetric synthetic aperture radar (PolSAR) images.

Theory and measure of certain image norms in SAR [PDF]

open access: yes, 1984
The principal properties of synthetic aperture radar SAR imagery of point and distributed objects are summarized. Against this background, the response of a SAR (Synthetic Aperture Radar) to the moving surface of the sea is considered.

Sparsity-driven sparse-aperture ultrasound imaging [PDF]

open access: yes, 2006
We propose an image formation algorithm for ultrasound imaging based on sparsity-driven regularization functionals. We consider data collected by synthetic transducer arrays, with the primary motivating application being nondestructive evaluation.
