Recognition of Signals from Pulsed Sources Based on the Form of Wavelet Spectra Constructed by the Principal Component Method
摘要
Abstract
A method for recognizing infrasound acoustic signals for two types of sources based on the analysis of the shape of their wavelet spectra is proposed. The idea of constructing this form is based on the principal component method. Morphological image analysis methods are used to search for characteristic areas. The proposed method makes it possible to effectively solve the problem of multiclass classification of acoustic signals.
