| 摘 要： | 在水下超声波测距仪对冰测距时，超声波必须在一定的入射角范围内测距仪才能接收到信号。在实验中，通过变换冰块的倾角来测出入射角临界值，数据处理结果显示，水下超声波测距最大入射角β为19°。

| Abstract: | During the measurement of the ice distance with the Underwater Ultrasonic Distance Measuring Equipment, ultrasound must be a certain incident angle range for the equipment to receive signals. In this experiment, the critical value of the incident angle was measured by changing the angle of the ice. The result of data processing shows that the critical value of the incident angle βis 19°. |
