空气中的超声波距离测量广泛用于中等或小分辨率的工业和商业低成本应用。应用的配置通常仅限于无源反射和 A-B 测量。本文对基于脉冲压缩的高分辨率超声波测距方法进行了综述。这种方法带来的改进包括良好的噪声抑制、可以并行操作多个系统而不会干扰串扰的影响以及高测量速率。修改后的配置和可用的高分辨率导致了总结的新应用。
Ultrasonic distance measurement in air is broadly used for industrial and commercial low cost applications with medium or small resolution. Configurations for the applications are usually restricted to passive reflection and A-B measurement. This paper gives a survey of the ultrasonic distance measurement method with high resolution based on pulse compression. Improvements resulting from this method include good noise suppression, possibility to operate several systems in parallel without disturbing influence of cross talk, and high measurement rate. Modified configurations and the available high resolution lead to new applications which are summarized.
