摘要
"不规则海域"是水平边界和海底边界形状不规则的海域。从边界混响产生的物理机理出发,以射线声学为基础,用Lambert散射定律计算海底和侧壁面的散射,建立浅海不规则海域混响强度模型。该模型仿真计算出的收发合置平均混响强度与实验数据测得的混响强度相符。该混响强度模型能准确地计算此类海域的平均混响强度。
The irregular sea is considered as the sea area with irregular horizontal and bottom boundary shapes and the complicated boundary conditions.By ray acoustics theory,the monostatic reverberation intensity simulation model for irregular sea is established by using Lambert＇s law to calculate scattering strength of the bottom and lateral wall.The monostatic reverberation intensity of the simulation model is in consistent with the reverberation intensity of the ex-perimental data.The simulation model can calculate reverberation intensity of the irregular sea area accurately.
