INTERMODE TIME-CORRELATION OF THE NOISE SOUND FIELD

Different processing procedures are considered for estimating the time correlation function for the sound field, which consists of signal an d additive noise. It is shown that, if a vertical array is used to sel ect individual modes, the determination of the cross-correlation funct ion of the modes allows one to detect a weak signal against the backgr ound noise. Time correlation functions are simulated for the specific transarctic acoustic path.
