|We have been proposed a fast and accurate sonar-ring sensor for a mobile robot. In this system, multiple time-of-flights of the echoes from the multiple reflecting objects are detected at each receiver in a single measurement. However, the echo from an object sometimes can not be detected, since it is hidden by the former echo. This is considered as an occlusion problem. When the time-of-flights measurement failed because of duration of the echo, target correspondence for accurate bearing angle measurement become more difficult. This paper discuss on this occlusion problem in a pulse-echo ultrasonic sensor with multiple echoes measurement.|
