Abstract
In conventional ultrasonic pulse-echo sensing, accurate target bearing measurement is often regarded as difficult due to the wide beam angle of ultrasonic transducers. However, measurement of the accurate angle is also very useful for many robot motions. We are developing a new sonar ring sensor which is possible to measure the accurate angle of the reflecting points. In this system, multiple transmitters and receivers are driven simultaneously, and differences of time of flight are used for measuring the accurate angle. This paper describes a simple wave memory system for detecting multiple echoes.
