The Response Model: An Operational Model for Towed Array Shape and Attitude Estimation Validated on TABAT Data

Abstract

An operational model for array shape and attitude estimation, based on the continuous measurement of heading and depth at a single position in the array, is presented. This model, which we call the Response model has been validated against the results from an independent method, that. makes use of the differences in travel times of explosive signals to the hydrophones. The heading, depth and travel time data was obtained during a sea trial. The effectiveness of the Response model is shown when it is applied to correct the sonar beamformer during a tow ship maneuver. It. is thus demonstrated that towed array sonar operations can be continued during maneuvering, which is of great operational advantage.
