Annotations languages:

In the article analysis of small UAV’s acoustic signals is done. Peculiarities of spectral estimates of UAV’s acoustic emission with electric engine and gasoline engine are shown. Periodograms of multi-propeller UAV’s are also presented. Approaches for such signals detection with acoustic means are proposed.
Keywords: acoustic monitoring, unmanned aerial vehicle, harmonics of acoustic emission, spectral estimate, periodogram
