摘要：
A new principle of LDV-systems is presented by using sequential filtration as a frequency lock loop (FLL) and likelihood Doppler frequency estimation. The FLL error signal is the value of filtering complex signal instant frequency. An optimal velocity estimate is obtained as an integral of the instant Doppler frequency.
