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 Cramér-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(More)
In this paper, the problem of two-dimensional (2-D) frequency estimation of a complex sinusoid embedded in a white Gaussian additive noise is addressed. A new frequency estimator based on a least square plane fitting of the estimated autocorrelation phase of the signal is derived. This algorithm requires a 2-D phase unwrapping step which can be easily done.(More)
This paper discusses a processing technique for LDV data, based on the use of two Kalman filters, enabling to detect the presence of particles and to infer their velocity. This method turns out to be suitable for the design of real-time integrated velocimeters. A first estimator, based on the use of a Kalman filter, deals with the amplitude of the Doppler(More)
