Arrays of sensors are used in many fields to detect signals, to resolve closely spaced targets, to estimate the bearing, the position, the strength and other properties of radiating sources whose signals arrive from different positions. The purpose of the work is described in the paper is to provide estimators which are used to localize acoustical sources by an acoustical array of sensors. These estimators are based on acoustic processing algorithms: the conventional beamforming, the minimum variance and the constrained Capon algorithm. It is shown that these adaptive algorithms can detect radiating acoustical sources which are not detectable by classical weighted arrays of sensors.
Key words: Acoustical array / Directivity pattern / Minimum Variance algorithm / Source localization.
