Doppler Effect removal based on instantaneous frequency estimation and time domain re-sampling for wayside acoustic defective bearing detector system.

Highlights: [•] A new method is developed to remove the Doppler Effect for ADBD system. [•] IFE and time domain re-sampling are employed in the method. [•] There is no pre-measurement carried out in the methods. [•] Technique has superior performance than the existing method. [•] Proposed new method has been verified by simulation and experimental cases. [ABSTRACT FROM AUTHOR]
