Abstract
FIELD: detection and determination of coordinates of noise sources. SUBSTANCE: signals are received by means of several motionless directed aerials. Spatial-frequency filters are formed and spectrum is subject to analysis at points of mutual crossings of spatial channels of several aerials. Areas to which the signal belongs and coordinates of their sources are determined by means of calculation of derived noisiness. EFFECT: improved precision.
