Optimum Bearing Resolution for a Moving Towed Array and Extension of Its Physical Aperture

Abstract

A continuing goal in sonar systems is to increase the detection range. As a result, towed arrays have been introduced in operational sonar systems, which has made the listening frequency range lower to achieve attenuation. Since the low-frequency regime includes mainly traffic noise, high bearing resolution is required for the angular separation of closely spaced ships.
