| 摘 要： | 海底混响是海洋混响的重要组成部分,采用模拟仿真进行验证分析,是仿真技术的一项重要应用。采用单元散射模型,研究在单发射阵元下,分布在同一直线上多个接收阵元接收的海底回波,忽略声波传播的相位起伏,只考虑振幅起伏,将传播损失、声吸收系数、海底反射损失、海底沉积层密度等参数带入海底混响仿真数学模型,仿真海底混响,使其更加接近海底的实际情况。

| Abstract: | Seabed reverberation is an important part of ocean reverberation,and adopting analog simulation in validation and analysis is a major application of emulation technology.Unit Scattering model is used to analyze seabed echoes received by multiple reception arrays that are distributed in the same straight line under the single array,ignoring phase fluctuation of acoustic wave propagation,only considering amplitude fluctuation,and introducing transmission loss,acoustic absorption coefficient,seabed reflection loss,density of seafloor sediment and other parameters into simulation model of seabed reverberation to bring the seabed reverberation simulation closer to actual situation in seabed. |
