For a given ground cover class, there is no straightforward way of expressing the joint distribution of a set of correlated radar images represented in amplitude or intensity. In this article we propose a general transformation method that permits incorporation of inter-image covariance while keeping a good fit to the marginal distributions. The approach is here studied for Gamma marginals, and the results of tests on a multitemporal series of ERS-1 multi-look images are presented.
