Abstract
In an embodiment, an acoustic projector includes an acoustic transmit transducer capable of producing a sound pressure radiation in response to a driver signal received from a transmit source, an acoustic receive transducer capable of producing a source level signal in response to receiving at least a portion of the sound pressure radiation, and a controller configured to monitor the source level signal and report the source level signal monitored.
Claims16
An acoustic projector comprising:
- a marine acoustic transmit transducer capable of producing a sound pressure radiation in response to a driver signal received from a transmit source;
- a voltage monitoring circuit configured to measure a voltage level of the driver signal;
- a current monitoring circuit configured to measure a current level of the driver signal;
- and
- a controller configured to monitor the measured voltage level and the measured current level to derive an indication of impedance of the acoustic transmit transducer based on the monitored voltage level and the monitored current level.
