Abstract
An apparatus and method for determining the range and bearing of an object rom a reference position. Sound energy emanating from the object and travelling through a water medium strikes spaced hydrophones located at the reference position. The signals produced in each hydrophone are correlated with the signals in each of the remaining hydrophones. The signals are correlated with a variable time delay between signals and the resulting maximum correlation output determines the range and bearing of the object.
