摘要

本文提出了一种方法，使我们能够区分墙壁和角落只使用一个单一的超声波发射。在本方法中，采用无旋转对称的超声光束。光束是由三个声纳组成的线性阵列产生的。它使不同声纳接收到的回波幅度在单反射和双反射时明显不同。

Objects distinguishing by using a flattened ultrasonic beam

This paper presents an approach allowing us to distinguish walls and corners using only a single emission of an ultrasonic wave. In the presented approach, an ultrasonic beam without rotational symmetry is employed. The beam is created by a linear array of three sonars. It causes the amplitude of echoes received by separate sonars to be distinctly different for a single and double reflection.
