Development of 3-D Underwater Radiated Noise Pattern using Hull Vibration Signature and Counter Detected Performance Analysis System

선체 진동신호를 이용한 3차원 수중방사패턴 및 피탐성능 분석 시스템 개발

This paper presents the system which can be predicted 3-D underwater radiated noise pattern using submarine hull velocity and can be analyzed the counter detected performance for threats in real time. To verify the developed system the tests were done in a water tank for structure like a submarine. The far field radiated noise pattern predicted using the developed system is compared with the result calculated using the near field measurement system, these results have shown good agreement.
