| 中文摘要: |
| 随着科学技术的飞速发展,对海洋声场作出合乎要求的快速精确预报,显得尤为重要。浅海平滑平均声场理论和深海广义相积分理论克服了经典的WKB近似在反转点发散的缺点,而且实现了声场数值预报的实时性要求,基于上述理论,进行海洋声场分析设备的研究和工程应用,对声呐的设计、使用及舰艇作战有重要意义。 |
| 英文摘要: |
| Today, it is important to predict the sound field fast and correctly. The smooth-averaged sound field technique and the generalized phase integral theory are effective methods for computing sound field in water. The two methods not only resolve the divergence problem at turning-point of classic WKB method, but also realize real time calculation. On the basis of these two theories, equipment for prediction and analysis can be developed. |
