Abstract

The influence of the self-noise of aeronautical sonobuoy on its detection performance are mainly analyzed in this paper. The types of sonobuoy self-noise are introduced in general and the estimation method of sonobuoy self-noise is given. The influence of self-noise on the signal-to-noise ratio of the acoustic signal collected by the buoy and the action distance of the buoy is analyzed quantitatively. The design methods and self-noise level of foreign sonobuoys for different noise sources are summarized. The analysis shows that the self-noise control of sonobuoy directly affects its detection performance, which is the key to buoy design. In engineering, necessary noise reduction measures should be taken to deal with different noise sources.
