中文摘要:
      本文对舰船辐射噪声的模拟技术进行了研究,给出了线谱、连续谱噪声、噪声调制的模拟方法,进行了计算机模拟,研制了可编程硬件模拟器。通过对模拟器输出信号的处理和分析,结果表明该模拟器能很好地再现舰船辐射噪声的典型声学特征。
英文摘要:
      The technology to simulate radiating noise from vessels is studied in this paper. The models to simulate noise with linear spectrum, continuous spectrum and amplitude modulation are provided, and computer simulations are provided too. The hardware structure of a programmable simulator is also proposed. By signal processing to the output of the simulator, the results show that the simulator can reconstitute typical acoustic signatures of radiating noise from vessels.
