| 在进行目标水下位置声学测量前，往往需要先对目标海域的声场信道进行测量计算，极大提高测量成本。文章探讨了同一地理位置处，使用公开声速数据和实测声速数据、不同时间段测量的实测声速数据场景下，声线到达结构的差异，从而量化分析时变深海声速条件对声线传播的影响，以期优化声学测量作业流程，降低实验成本。计算结果显示，当存在直达声线时，临近几日测量的声速数据即可满足声传播距离测量的要求，否则，需要进行重新测定。 |

| Before the acoustic measurement of the target location in deep ocean, it is necessary to measure and calculate the acoustic field around Designated area, which greatly increases the measurement cost. In order to optimize the acoustic measurement process and reduce the experimental cost. This paper find a way to quantitatively analyze the influence of the sound speed in deep ocean to sound propagation. discusses the difference of sound arrival structure when getting SSP in different time , also comparing with the public sound speed data when figure sound arrival structure. The calculation results show that when there is a direct sound ray, the sound velocity data measured within a few days can reach the requirements of sound propagation measurement; otherwise, it needs to be remeasured. |
