| Abstract: | This paper discusses a processing technique for Laser Doppler Velocimetry (LDV) data, enabling to detect and localize in time domain the presence of Doppler bursts in case of acoustic excitation. A joint detection-estimation scheme based on the use of the Wavelet Transform (WT) realized in the time-scale domain is proposed. The performances of the detector are characterized with ROC (Receiver Operating Characteristic) curves. Finally, the estimator performances are studied by means of Monte Carlo trials obtained from synthesized LDV signals. | ||
