Abstract

The article considers algorithms for determining the location of a sound source (intruder) using a system of distributed acoustic sensors in two-dimensional and three-dimensional space, in particular, the simple triangulation algorithm and the triangulation algorithm when the sound source is displaced. The algorithms proposed in the paper can be used to build auxiliary security systems to prevent theft of information and valuable property. Modeling of the influence of a source of harmonic acoustic impact on a system of distributed acoustic sensors was carried out, according to the results of which the distance from the optical fiber to the location of the source of harmonic acoustic impact (intruder) could be determined with an error of up to 10-15% or less.
