Estimators and distributions in single and multi-look polarimetric and interferometric data

Provides a nearly complete analysis of the key distributions encountered in single and multi-look polarimetric and interferometric synthetic aperture radar (SAR) data, under a Gaussian or multi-variate K distribution model. It contains new analytic results on the moments of phase difference in single look data, and on multi-look distributions of amplitude and phase. As yet no analytic results for the moments of multi-look phase difference have been found, except in limiting cases. The maximum likelihood estimators of the covariance matrix of two jointly Gaussian channels is derived, along with their asymptotic variances. A more complete discussion of these ideas is presented by Tough et al. (1994)
