Description of time-varying noise processes with applications to aircraft flying-over noise

  • On the basis of spectrum moments description of a signal, Evolutionary vector is developed to destribe time-slowly-varying noise processes. It can describe main time-varying properties of a signal. Applications to aircraft flying-over noise are presented.
