SYSTEMS AND METHODS FOR REDUCING FALSE TARGETS IN ULTRASONIC RANGE SENSING APPLICATIONS

摘要

An ultrasonic range sensor comprises at least one transducer adapted to generate an ultrasonic pulse having a first axis of transmission and detect a reflected signal that is associated with the ultrasonic pulse and propagates along the first axis of transmission. The ultrasonic range sensor also comprises a deflecting region adapted to reflect the reflected signal along a second axis different from the first axis of transmission. In one embodiment, the second axis is deflected from the first axis by a non-zero angle determined by a characteristic of the deflecting region.
