Abstract
A complex covariance spectral moment estimator for Doppler processing is presented as a means of reducing data acquired by a ground-based optical radar (lidar) before estimating a volumetric wind field. This estimator is equated to the first-order complex maximum entropy mean frequency estimator. It is also shown that the first-order estimator is the only order for which the complex maximum entropy frequency estimator is unbiased.
