Abstract :
An adaptive mean frequency estimator is proposed which can be fitted to the specific characteristics of a given Doppler signal by trimming a single parameter. It allows to optimize the compromise between the bias and the variance of the mean frequency estimation. The performances of this estimator are shown superior to those of the usual correlation angle estimator used for color flow mapping.
