Popis:	Experimental measurements of signal coherence and array signal gain are reviewed for both deep and shallow water sound channels. The signal gain is related to single path or modal coherence lengths through well‐known relationships in the statistical theory of antennas. Signal gain measurements in the transverse and longitudinal directions are proffered as the optimum measures of coherence lengths for both broadband and narrow‐band signals. Using this technique measurements (
