ABSTRACT

In the paper the method for increasing of accuracy when applying method of circles for acoustic localization of sound sources is suggested. The matter of the proposed method is compensation of temperature effect by proper selection of appropriate part of frequency spectrum of acoustic signal.

Key words: acoustic localization, explosions, error, temperature, humidity.
