Point Source Localization Sonar System and Method

Abstract

A matched-field based sonar system and method of use that supports real-time, three-dimensional acoustic source localization using a mobile, horizontal- array. The system receives and processes acoustic array, non-acoustic array, and own-ship navigational data in the matched-field process (MFP) Driven by own-ship and array status, a global bathymetry database and an acoustic environmental model are used to generate replicas for the MFP. If a three-dimensional tracker is assigned, then the tracker will steer the search region to maintain contact on the target of interest. Displays are provided to the user including tracker displays (which provide tracker information), MFP ambiguity surface displays (which support contact localization) and non-acoustic and navigational displays. A control interface allows a user to control the search region in bearing, range, depth, and frequency; assign the three-dimensional tracker function; and control display processing.
