Acustic sensor for localization

摘要

A system for the localization of target objects using acoustic signals is disclosed. The system comprises an acoustic transducer; acoustic reflecting means; processing means and output means. The transducer is adapted to transmit acoustic signals to a target object, receive superposed echoes from the target object, directly from the target object and indirectly, reflected by said acoustic reflecting means, and transmit an electrical signal corresponding to the received superposed acoustic signal to said processing means. The processing means is adapted to compute the position of the target object and output the position through said output means.
