Joint Statistical Distribution of Multi-Baseline SAR Interferograms

In this paper we ebaluate the joint probability density function of dual beselines Synthetic Aperture Radar (SAR) interferograms, obtained from three correlated interferometric images. The evaluation exploits the Gaussian model for the complex SAR images, takes into account the correlation of all the images, and then of the interferograms, and does not use any approximation. This problem is of great interest in statistical DEM estimation methods.
