摘要

研制了一种具有144个发射单元的高功率超声阵列发射机，用于空气中三维测量。超声波频率为40 kHz，在空气中距离5 m处获得了126 dB的声压级。该值比使用单个发射元件获得的值高约32 dB。研究了阵列发射机的特性，并与仿真结果进行了比较。实验结果与仿真结果吻合较好。

Characteristics of a high power ultrasonic array transmitter in air

A high-power ultrasonic array transmitter with 144 transmitting elements for 3D measurements in air has been developed. The sound pressure level of 126 dB was obtained at a distance of 5 m in the air with an ultrasonic frequency of 40 kHz. This value is approximately 32 dB higher than that obtained using a single transmitting element. The characteristics of the array transmitter were studied and compared with simulation results. The experimental results were in good agreement with the simulation results.
