Modelling of maximum likelihood estimates algorithms of the laser doppler systems frequency at finite number of counts

Algorithms of receiving maximum likrlihood estimations of the laser Doppler systems signal frequency on two and three its complex readout and also the results of computer modelling of these algorithms are presented. It is shown, that estimations of frequency practically are not displaced, and addition of 3-rd readout essentially (in three-four times) increases accuracy of measurements.
