接收基阵垂直指向性引起的附加声传播损失
Additional sound transmission loss resulting from directivity in the vertical plane of a receptive array
  
中文摘要:
      具有垂直方向指向性的接收基阵对入射声波有方向加权效应。本文在该类基阵声纳方程的基 础上,导出了附加声传播损失的具体表式,讨论了深度-声速梯度对附加传播损失的影响。最后给出 负声速梯度条件下的算例,计算结果与海上试验吻合较好。
英文摘要:
      The receptive array with directivity in the vertical plane has weight effect on the incident wave. In this paper the formula of additional sound transmission loss is derived, and the sonar equation for the array is accordingly modeled. The effect of depth-sound speed profile on the additional sound transdssion loss is discussed. An example with a negative gradient depth profile of sound speed is presented, where the calculated values are shown to be in agreement with the experimental data.
