Error in Finding Direction of Arrival Using a Linear Array Due to Scattering from an Elastic Cylinder

  • Published 2012

Abstract

Sonar domes, with stiffeners, house acoustic transducer arrays that are used to determine the direction of arrival of nearly plane acoustic waves generated by distant sources. Scattering of the waves, by the stiffener, disturbs the pressure field and causes a difference between the actual and measured directions of arrival. The errors, when using energy and… (More)
