Abstract
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.
