基于声速梯度的声纳浮标工作深度选择
|
摘要
海洋条件复杂多变,声传播损失TL不仅随距离变化,而且还随着深度变化,这就意味着声纳浮标在工作时,位于不同的深度,其探测距离是不一样的。根据不同的实际海洋环境,将浮标换能器基阵置于最合适的深度进行工作,才能发挥其最大的探测能力。在各类影响因素中,声速梯度是决定声纳浮标工作深度的重要因素,在分析声速梯度的影响因素和海洋声速垂直剖面的几种类型的基础上,利用射线理论,通过实例计算得到了黄海海域特定环境下的声线剖面。从而得出以声线剖面图为依据,根据潜艇目标可能的航行深度,选择浮标最佳工作深度的方法。
The marine environment is complicated. The loss of sound propagation would be changed not only by distance,but also by the depth change. These mean that the detection range of sonobuoy would also be changed by different depth. According tothe different Marine environment,the best detection capability can be realized by placing the buoy transducer array at the most ap-propriate depth. In all kinds of influence factors,the sound velocity gradient is an important factor which decided the sonobuoy workdepth. Based on the analysis of the influencing factors on the velocity gradient and ocean sound velocity,on the basis of severaltypes of vertical section,using the theory of ray,sound sections are obtained by calculation of the specific environment of the yellowsea. The method of selecting the best working depth of the buoy is given by the sound sections and the possible depth of the submarine.
