MATHEMATICAL-MODELING OF THE SPATIAL-TEMPORAL CORRELATION-FUNCTION OFTHE SOUND FIELD IN AN ARCTIC WAVE-GUIDE

The spatial-temporal correlation function of a noise sound field repre sented by a mixture of a signal and an interference is modeled. The re ception by a point hydrophone and a vertical array selecting a referen ce mode is considered. The envelope of the correlation function of the array and hydrophone signals is investigated. It is shown that, by pl acing the reference hydrophone at some specific depths, one can select a weak signal against a high-level ambient noise.
