The Shielding Characteristics of a Surface-Ship Stern Baffle.
Abstract
The results of an investigation concerning the shielding characteristics of a surface-ship, stern baffle are presented. A mathematical model previously developed to analyze the effects of a baffle on the performance of a sonar transducer has been used to characterize the influence of a stern baffle on the transducer noise level due to a plane wave incident from the direction of the ship screws. Quantitative results are obtained for a two-dimensional configuration with parameters appropriate to the AN/SQS-26 configuration. The influence of transducer-baffle spacing, baffle curvature, and baffle coating on the transducer environment has been investigated. The results are given in terms of constant pressure contours in the shadow region of the baffle, i.e., the vicinity of the transducer. (Author)
