摘要： A system for underwater survey operations such as sea-bed, ice-mapping or pipeline tracking comprises an autonomous unmanned submarine vehicle having propulsion and steering means (4-8, 10, 11), a navigation system (38) comprising motion sensing and positioning means and an adaptive autopilot system (41) to propagate the vehicle through a predetermined submarine trajectory. A synthetic aperture sonar system (42) includes a sonar transmission and receiving array (43) of a length defining a limited physical aperture arranged on a surface part (32) of the vehicle to capture echo-signals in response to emission of sonar signals through a part of said trajectory defining a synthetic aperture of a length several times greater than said physical aperture. The autopilot system (41) is controlled to register any deviation of the propagation of the vehicle from said trajectory and provide a correspondingly corrected description of the predetermined trajectory within a margin of a fraction of the wavelengh of the sonar signals. Sets of echo signal values captured within said synthetic aperture are stored in memory means (44) and signal processing means (54-57) is provided for processing said stored sets and generating higher resolution image information data corresponding thereto.

摘要： PCT No. PCT/NO97/00064 Sec. 371 Date Oct. 8, 1998 Sec. 102(e) Date Oct. 8, 1998 PCT Filed Mar. 5, 1997 PCT Pub. No. WO97/41454 PCT Pub. Date Nov. 6, 1997There is provided an acoustic source especially for use in seismic studies at sea. The acoustic source has a longitudinal axis and sound emitting surfaces adapted to be put into sound emitting movements towards and away from each other by use of a drive unit. The sound emitting surfaces comprise two curved plate members having upper and lower ends essentially symmetrically positioned in relation to the longitudinal axis of the acoustic source, and forming a convex cross section with their respective upper and lower edges converging towards each other. The upper and lower edges of the sound emitting surfaces, respectively, are connected to each other with two corresponding side elements, the side elements each being connected to at least one hinge stretching along at least a part of the length of the source. The acoustic source further comprises a rigid frame for supporting the drive unit and comprising at least two rigid slide rods slidingly attached to the side elements with slide bearings for permitting relative axial movement of the slide rods with respect to the side elements. Hinges connected to the side elements provide a direct connection between the upper and lower edges, respectively, of the sound emitting surfaces.

摘要： The invention provides a seismic transmitter source system which includes a floatation device that contains a plurality of air tight chambers in a serial connection. A separate one way check valve is placed between each adjacent pair of the chambers. Pressurized air is continuously supplied to an end chamber. The one-way check valves enable the air to pass to the remaining chambers in one direction. A transmitter subarray containing a plurality of spaced apart transmitters is suspended from the floatation device by means of severasl pivotly connected links. The front end of the transmitter array is connected to a point near the front end of the floatation device. During operation, the seismic transmitter source system is pulled from a tow point located at the front of the floatation device, pulling both the floatation device and the transmitter subarray in substantially a horizontal straight line position while maintaining the transmitter subarray at a near constant depth below the water surface.

摘要： The invention relates to a method of estimating the acoustic signatures of seismic sources, used in underwater seismic surveying, in order to obtain more accurate data on their wave form in the far field. The pressure response produced by an array of sources is sampled by a hydrophone array larger in size than that of the array of sources and positioned relatively far from the array of sources; the individual response of each of the hydrophones in the hydrophone array is measured separately, and the wave form of the source array signature is calculated from these measurements. The hydrophone responses can be analysed in order to give a numerical reconstruction of the configuration of the source array together with its reflected image at the water-air boundary, or they can be extrapolated directly to the location of interest in the far field.

摘要： In order to use near-field measurements to obtain signature of a signal penetrating seafloor in a shallow water surveyed area, the water-bottom reflections' effect is removed. The removal is performed by obtaining first a far-field initial estimate from stacked primary pulses in the near-field measurements, and then estimating water-bottom reflection portions for different depths using differences between the near-field measurements and the far-field initial estimate. The signature of the air-gun for each shot is then deblended from the near-field measurement for the shot using the one of the water-bottom reflection portions according to a water-bottom depth associated with the shot location.

摘要： A coherent sound source is provided for marine seismic surveys. An underwater sound projector for producing time-harmonic waveforms comprises two pistons positioned on either side of an electro-magnetic force generator substantially having mechanical and magnetic symmetry about its geometric center thereby creating a virtual node to substantially cancel reaction loads that occur when the pistons are actuated. The underwater sound projector optionally also includes control systems to improve the fidelity of the force generator, provide pressure compensation to the pistons, finely adjust the static position of the pistons, and change the depth and roll when it is configured as tow body. A plurality of underwater sound projectors can be configured in an array. A load-bearing umbilical can connect the underwater sound projectors to a ship, transmit electrical power to each array element and serve as a duplex data transmission medium to route commands from the ship to the projector and report machinery status to the ship.

摘要： In a method for determining absolute position under water of a submersible vessel (1) having a dead reckoning navigation system and receiving acoustic signals from a reference station (19), signals are received from one reference station in several positions (15-18) of the vessel. Estimated absolute positions of the vessel are calculated using range data and relative position data. Range rate derived from the signals are preferable utilised. In a method for scanning an underwater survey area, the absolute position of a vessel (1) is intermittently being determined according to said method. The reference station may be placed at a fixed absolute position (19), or on the surface of the water, preferably in a buoy or a vessel. A system for determining the absolute position under water of a vessel comprises: acoustic communication means in a reference station and on board the vessel; a dead reckoning navigation system on board the vessel; and computing means.
