A model for seafloor reverberation simulation

  • 摘要: 提出了一种新颖的海底混响仿真工程实现模型.它是基于单元散射的理论,通过模拟海底混响形成的物理过程实现仿真,具有仿真效果好,工程上易于实现的特点.根据该模型实现的多通道海底混响模拟器功能强、柔软性好,所产生的海底混响仿真信号无论是在形式上还是在统计特性方面与实测海底混响相比较都有很好的一致性.此外,该模拟器还可以作为目标模拟器或者相控/束控信号源使用.

     

    Abstract: This paper presents a new model for the implementation of seafioor reverberation simulation.Based on the element scattering theory,the model,which was charaterized by both good simulating results and simplicity of the implementation,was developed by means of sim-ulating the generating process of the seafloor reverberation.The'Space-Time'transformation technique was also developed as one of the main features of the research project,which simplified the realization of the model significantly.The multichannel seafloor reverberation simulator thus developed is flexible with multifunction.Waveforms and statistical properties of the seafioor reverberation simulated are consistant with that of the seafloor reverberation collected in the real environment.Besides,it can be used as a target simulator simulating the movements of underwater acoustic targets or as a signal generator generating phase-controled signals.
