舰船辐射噪声模拟器设计

摘要

文章首先分析了舰船辐射噪声的频谱特性和声学特征,给出了线谱和连续谱的合成方法,随后从工作原理、硬件结构和软件流程三个方面介绍了模拟器的设计。该模拟器具有结构简单、可靠性高的优点,能够逼真模拟船辐射噪声的线谱和连续谱信号,可用于在水声装备的研制、仿真和试验。%The spectral properties and acoustic properties of ship radiated noise are analyzed.The method of combining line spectrum and continuous spectrum is given.Then the noise simulator is designed in details from three aspects:the working principle of the simulator,the hardware components and software process.The simulator which has the advantages of simple structure and high reliability can realistically simulate the line spectrum and continuous spectrum of ship's radiated noise.It can be used in the development,simulation and testing of underwater acoustic equipment.
