摘要
介绍了超声波测距和超声波测速的基本原理及应用。根据超声波探测技术中的测距和测速原理设计制作了相关实验组件。利用数据采集系统对超声波测距、超声波测速中的时间延迟、距离、频移量进行了测量,给出了声速、计算距离,相对速率等结果及误差分析。
The principles and the applications of the ultrasonic measuring velocity and the ultrasonic measuring distance were presented. Some components were made according to the above principles and applications. The data including the time delays, distances and the frequency shifts on the principles and applications were measured through the data collection system. The results about the sound velocity, the theory distance and the relative velocity were given and the errors were analyzed.
