Abstract
The motion of an object is characterized by transmitting acoustic signals over first and second transmitter-receiver channels. Information relating to signals received over the first channel is compared with information relating to signals received over the second channel, to identify a similar pattern in both channels arising from reflections from the object. A relative timing difference between the channels, associated with the similar pattern, is used to characterize the motion of the object.
