| 中文摘要: |
| 蛙人探测声呐的探测性能及作用距离不仅与目标海区的声速剖面和自身性能参数有关，还与其布放深度有关，其布放深度的选择对于水下目标探测具有重要意义。以射线跟踪理论为基础，建立了基于探测概率感知的声呐性能评估模型；提出了一种声呐布放深度自适应优化算法，该算法以不同准则进行两次筛选优化后可得到声呐最佳布放深度。仿真结果表明：在不同水文情况下，所提优化算法可有效调整声呐布放深度，从而提高声呐对目标的探测性能。 |
| 英文摘要: |
| The detection performance and detecting range of diver detection sonar are not only related to the sound speed profile and work parameters, but also related to its underwater depth. It is important for underwater target detection performance to select deployment depth. The sonar performance evaluation model using detection probability perception is established based on ray tracing theory. An adaptive optimization algorithm for sonar underwater depth is proposed. The optimal underwater depth of sonar can be obtained by twice screening with different criteria. The simulation results show that the optimization algorithm is effective and can improve the target detection performance of the sonar. |
