| 中文摘要: |
| 潜用拖曳线列阵声呐在拖曳过程中，随着潜艇的运动状态变化，其线阵阵形会产生一定的畸变。速度越慢，其畸变幅度越大。阵形畸变，将影响声呐的探测性能。为有效提高拖曳声呐的探测能力，需对阵段不同拖曳状态进行阵形变化研究。基于以上研究需求的基础上，使用随机共振技术和阵元多普勒频移特性，在实验室或湖上构建了阵形估计系统，该系统可对不同拖曳状态的测试阵段实时地精确估计阵形，满足拖曳线列阵声呐阵形估计技术研究的需求。 |
| 英文摘要: |
| The array shape towed under water will generate a certain distortion if the movement of towing device changes. And, the slower the towing speed, the greater the distortion magnitude, obviously the distortion affects the detection performance. To improve the detection performance of the towed array, how the array shape changes in different towing states needs to be researched. This paper introduces the research results based on these demands, and proposes using the stochastic resonance (SR) technique and Doppler shift character to build a shape estimation system of towed array. This system can provide precise estimates of the array shape in real time to meet the needs of shape estimation technique for towed array sonar. |
