Noncoherent Radar Detection in Correlated Pareto Distributed Clutter

Radar detection in the presence of spatially correlated Pareto distributed clutter is examined. It is shown how an order-statistic-based sliding window detection process must have its threshold set in order to achieve a constant false alarm rate. A particular multivariate Pareto distribution is constructed, based upon a compound Gaussian model with inverse gamma texture, whose pairwise marginal distributions have a general correlation. A specific example is then used for performance analysis.
