The Effect of Narrowing Source Beam on Convergence Zone Width,

Abstract

This note presents some ray computations to demonstrate how restricting the vertical angle at which rays are emitted at the source diminishes the width of the convergence zone. This is not a complete study and the note is not to be considered as a formal report. These computations were done to aide in evaluating a proposed sonar system. Since they shed some light on the relation between vertical beam width and zone width, the results are summarized here. The sound velocity profile is from the area 30 deg. N 120 deg. W as measured in February.
