摘要
The performances of fast time delay estimators, the hybrid-sign, and the polarity coincidence have been evaluated for general signal and noise spectra and compared to the classical direct technique. Some physical spectra have been analyzed in particular for the white noise case: polarity coincidence time delay estimation has been verified to exceed hybrid sign time delay estimation for large SNR and for high-resolution processing. Simulation results confirm the theoretical analysis.
