22 January 2002 Intensity-weighted phase-derivative statistics
Author Affiliations +
We have previously shown that amplitude weighting can improve the accuracy of measurements of the frequency offset of a signal contaminated by multiplicative Gaussian noise. We have investigated the more general non-Gaussian case through study of the statistics of a simple phase-screen scattering model and derived formulae for the low-order moments of the intensity-weighted phase-derivative. In this paper we extend numerical simulation of the problem to the case of a phase screen with Kolmogorov spectrum. We also report the results of some preliminary experimental measurements.
