The methods of Doppler frequency estimation for laser systems of flows investigation

The methods of an estimation of Doppler frequency instant values of the laser Doppler anemometer and vibrometer signals are discussed. The use results of the Hilbert transformation, the discrete count and the wavelet-analysis methods for restoration of dependence of instant frequency from time for various mathematical models of signals are considered.
