Abstract :
Signals from distant sources produce intersensor delays in towed arrays which may have their measurement variances improved when all possible sensor-pair measurements and a priori knowledge of range are taken into account. Improvement factors are defined and plotted versus signal-to-noise ratio and versus number of sensors in the arrays. Clustered versus equally spaced sensors is another aspect investigated. Analytical results are obtained for three sensors.
