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 split beam correlation methods, in finding the direction of arrival (DOA), caused by the presence of a stiffener in the form of a circular… CONTINUE READING
