ABSTRACT:
A pulse-echo sonar scanner for a mobile robot includes a transmitter which generates a pulse signal, an acoustic transducer which transmits and receives acoustic signals, a receiver, means for determining performance characteristics of the transducer for a given pulse, means for storing the performance characteristics, and means for determining threshold levels for an echo based on the stored performance characteristics.
