Abstract
A processing procedure is described that estimates the frequency and the arrival time from signals measured with a laser Doppler anemometer (LDA) and additionally, the phase difference and the time delay of signals measured with a phase Doppler anemometer (PDA). The basis of the estimation procedure is a wavelet transform. The procedure described works iteratively, alternating between the time and the frequency domain. The performance of the estimator is compared to other estimation procedures and the Cramér-Rao lower bound using numerical simulations.
