Abstract
A survey system including a transmitter, receiver, projector array and hydrophone array transmits and receives sound waves to perform one or more survey missions.
Claims19
A sonar system including a multibeam echo sounder for conducting survey operations, the sonar system comprising:
- a transceiver configured to excite a single file array of projectors with a common signal;
- the projectors configured to project an elongated transmit beam that ensonifies an entire swath;
- the transmit beam for conveying multiple signals in separate frequency bands, each frequency band enabling a different measurement;
- multiple elongated receive beams intersect the swath and transport echo information from scattering centers at each intersection;
- and,
- the echo information for determining plural different measurements based on the frequency band of the return.

A sonar system survey method using a multibeam echo sounder, the method comprising the steps of:
- exciting a single file array of projectors with a common signal;
- ensonifying an entire swath via an elongated transmit beam from the projectors;
- conveying multiple signals in separate frequency bands via the transmit beam;
- intersecting the swath with multiple elongated receive beams that return echo information from scattering centers at each intersection;
- and,
- determining plural different measurements based on the frequency bands of the returned echo information.
