| 摘 要： | 在详细研究了舰船辐射噪声特性的基础上，对其线谱、连续谱和调制包络进行了建模与仿真。连续谱采用自适应FIR滤波方法仿真，调制包络由高斯脉冲串组成。通过对仿真出来的信号进行功率谱分析与DEMON谱分析，该仿真能较好地体现舰船辐射噪声的基本声学特征。

| Abstract: | The fundamental characteristics of ship-radiated noise are studied in this paper. The line spectrum, continuous spectrum and amplitude modulation are modeled and simulated. Continuous spectrum simulation is performed through adaptive FIR filter method. Amplitude modulation is formed by Gaussian pulse serials. The simula tion can reflect typical acoustic characteristics of ship-radiated noise by processing and analyzing the simulated signal. |
