The article analyzes the principles of constructing the acoustic systems for the determination of the object’s position on a plane. The authors introduce a developed algorithm for identifying the position of the sound source on a plane according to the data from four acoustic direction finders. In order to increase the accuracy of estimation we suggest using a method of minimal sum of normals based on the least squares method. The work describes a developed mathematical model of the position finder input signal and the entire system’s functioning. We estimate the accuracy of determining the object’s position according to the above mentioned algorithm.
