Comparative analysis of the smoothing algorithms of frequency overshoots in laser doppler anemometry

The new way of the multiparticle Doppler signal frequency overshoots smoothing based on restriction of the received frequency values with the set threshold is offered and investigated. It is shown that in the absence of noise the gain in accuracy can reach 1,7 times, and in the presence of noise to 3 times.
