Abstract
In an acoustic pulse-echo ranging system, the transmitter and receiver, which respectively generate pulses of acoustic energy and receive reflections of the same, are electronically tuned to determine their operating frequency, the electronic tuning being controlled responsive to stored data relating to a particular transducer being utilized to transmit and receive a pulse. A single transmitter and receiver can be utilized to service a number of different transducers, being automatically tuned to an appropriate frequency for each transducer as it is used to transmit and receive a pulse. The system can verify the nominal operating frequency of each transducer, and can also adjust the operating frequency used with any particular transducer to optimize its performance.
