Abstract: The sonar array system includes a receive array of hydrophones and a transmit array of acoustic projectors disposed on a common axis. The sonar array system can be coupled to a ship and deployed and recovered from a single winch and through a single ship hull penetrator. When towed through water by the ship, the sonar array system provides a substantially horizontal transmit/receive array.

Abstract: A system and method for generating acoustic source energy in marine seismic operations. A plurality of acoustic energy sources are integrated within seismic streamers to facilitate deployment, power distribution and signal communication. The acoustic energy sources can comprise slotted cylinders activatable with piezoelectric elements. By providing an arrray of lightweight, energy efficient acoustic energy sources throughout a seismic receiver array, both zero-offset and far-offset reflection data can be recorded. The acoustic energy discharge can be swept over a time interval, or steered in a selected pattern throughout the arrray, to significantly reduce the impulse energy released into the water. The reflected signals can be compressed back into an impulse for subsequent data processing. Bi-static reflections can be generated simultaneuously with the zero-offset source-receiver locations to improve the vertical and horizontal resolution of data.

Abstract: A marine seismic fiber optic acoustic sensor system having internal mirrors (14) with a low reflectivity written into the fiber (12) to form a series of continuous, linear sensors (16) incorporated in a single fiber, each sensor bounded by a pair of internal mirrors. A pulsed laser (20) provides optical signals to the fiber at a pulse width less than twice the travel time to assure that there will be no phase or frequency modulation of signals returned from the sensors and reflected optical energy is returned through the same fiber to an optical coupler (24) where it is input to a compensating interferometer to produce interference signals which are then time division multiplexed to produce signals corresponding to acoustic signals received by each mirror bound sensor. Calibration to remove local temperature effects is provided by using a desensitized reference fiber with internal mirrors identical to the sensitized fiber, by a piezoelectric stretcher built into the fiber or any other conventional calibration technique.
