| 中文摘要: |
| 声呐系统进行水下导航及目标探测时，需要大规模布阵形成换能器阵列来实现，所需硬件以及信号处理的复杂度较高。而在螺旋声场中，由于方位角和声压相位角是线性对应的关系，所以仅由一个螺旋信标就能实现对水下目标的探测。因此，本文设计了一种能够产生螺旋声场的圆管换能器，通过comsol有限元软件仿真，证明了该圆管换能器可以产生螺旋声场。在此基础上，进行水池实验对螺旋声场的性质进行了验证，为进一步设计出用于水下导航以及目标探测的声呐系统打下了基础。 |
| 英文摘要: |
| When sonar system is used for underwater navigation and target detection, it needs a large scale array to form a transducer array, which requires high complexity of hardware and signal processing. In the spiral sound field, because the azimuth angle and the sound pressure phase angle are linearly corresponding, the underwater target can be detected only by a spiral beacon. Therefore, this paper designs a spiral tube transducer which can generate spiral sound wave. Through the simulation of comsol finite element software, it is proved that the spiral tube transducer can generate spiral sound field with high quality. On this basis, the properties of spiral sound field are verified by pool experiment, which lays a foundation for further designing sonar system for underwater navigation and target detection. |
