A method for ASW detection and localization using two horizontally separated vertical line arrays is applied to the TAGEX 87 deep water data set. The method consists of beamforming the two vertical arrays and crosscorrelating the beamformer outputs. Application of the method to a 5 hr time period during which several ships pass near the two arrays results in clear detections of two ships. A correlagram fining procedure is used to localize the ships, and simulated beam-cross-beam correlagrams agree well with the measured data. Simulated signals from quiet sources are injected into the measured data, and detectability as a function of range and source level is investigated.
