I ran monte carlo simulations for Rayleigh samples and this estimator does not come close for small n. For example, with sigma = 1.0, using sample sizes of 2 the average value of the estimate is 0.50 (over 1MM iterations). The parameter K is known as the Ricean factor and completely specifies the Ricean distribution.

An additional increment of the Rayleigh number leads to a chaotic regime in a fully developed turbulence.
