Abstract
A method of processing the signals of laser Doppler anemometers using wavelet transformation is considered. The errors of Doppler frequency estimation obtained from an analysis of the wavelet spectrum of the signal are calculated and the influence of a number of parameters on these errors is investigated. Recommendations for performing measurements are given.
