潜艇辐射噪声水平指向性测量方法

当前潜艇水下辐射噪声测试主要还是以水声测量技术为主要手段。本文探讨了1种新的测量潜艇水下辐射噪声水平指向性的方法,思路新颖,简单实用,工程可行性强,能全面准确地获得潜艇辐射噪声在单频和频带内的水平指向性。通过测量分析潜艇水下辐射噪声的指向性,能深刻理解潜艇水下辐射噪声场空间分布的规律,初步判定潜艇辐射噪声源的部位及其频率特性,为潜艇声隐身技术的发展和水中兵器的研制提供科学依据和有利支撑。

Research on measuring method of submarine radiated noise horizontal directivity

Currently underwater sound measurement technology is the main means of submarine radiated noise test.In this paper discussed a new practicability method of measuring horizontal directivity of submarine radiated noise,that can roundly understand the horizontal directivity of submarine radiated noise in monofrequent and broadband,perceive the regularities of distribution of submarine radiated noise field,approximately locate the position of main noise source and frequency character,that is important sense to the development of submarine’s acoustic stealth and the investigation of underwater weapon.
