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。

Abstract: 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 finite element software, it is
demonstrated 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.
Keywords: Orthogonal dipole; Spiral sound field; Phase controlled excitation; Finite element simulation
