Abstract :
A maximum-likelihood estimator for the pulse-to-pulse correlation coefficient r of Rayleigh-distributed clutter components is considered. For r greater than 0.9, an approximate computationally feasible estimator is derived. Results of Monte Carlo simulation indicate that the approximate estimator is only slightly inferior to the maximum-likelihood estimator.
