              <p>This paper considers the problem of estimating acoustic particle velocity and convection velocity in the air by means of laser Doppler velocity (LDV) measurement. Closed-form for the Cramer-Rao bounds (CRB) on the estimates of the velocity parameters, for a sine wave excitation, are derived and simplified expressions are given. Moreover, a maximum likelihood estimator (MLE) and a signal phase derivative-based estimator (DBE) are proposed. Finally, estimator performance is illustrated by means of Monte Carlo simulations obtained from synthesized signals and the statistical efficiency of the MLE is checked out.</p>
