Abstract:Vibrometry offers the potential to classify a target based on its vibration spectrum. Signal processing is necessary for extracting features from the sensing signal for classification. This paper investigates the effects of fundamental frequency normalization on the end-to-end classification process [1] . Using the fundamental frequency, assumed to be the engine's firing frequency, has previously been used successfully to classify vehicles [2,3] . The fundamental frequency attempts to remove the vibration vari… Show more
