Popis:	A new principle of LDV-systems is presented by using sequential filtration as a frequency lock ioop (FLL) and likelihoodDoppler frequency estimation. The FLL error signal is the value of filtering complex signal instant frequency. An optimalvelocity estimate is obtained as an integral of the instant Doppler frequency.Keywords: Laser Doppler anemometry
