Acceleration-based Dopplerlet transform-Part Ⅱ: Implementations and applications to passive motion parameter estimation of moving sound source

摘要

The acceleration-based Dopplerlet transform developed in Part I is applied to passive estimation of the motion parameters of moving sound sources. The problems considered are: (1) accuracies of the estimated Dopplerlet parameters; (2) application-specific fast implementation. The experimental results using synthetic, land, air and underwater acoustic signals are presented to validate the acceleration-based Dopplerlet transform and to verify the effectiveness of the passive estimation scheme using a single sensor.
