Aural Spectrum Analysis for Naval Vessel Radiation Noise

Abstract

A passive long wave cochlea model is applied to extract audial feature of naval vessel radiation noise. Based on the model, a two dimensional time space distribution Spectrum of noise signal is calculated. Four one dimensional features with simple form are presented. The experiment results shows that the features based on cochlea model is consistent with auditory perception of noise signal. The approach is a new method to extract feature for passive sonar target recognition.
