摘要： A coherent sound source is provided for marine seismic surveys. An exemplary underwater sound projector comprises a plurality of pistons actuated by an electromagnetic force generator having components comprising a stator, armatures, electrical coils, and permanent magnets. The pistons and the components are arranged to create mechanical and magnetic symmetry about a geometric center of the projector to reduce reaction loads that occur when the pistons are actuated. The stator and the armatures have magnetic poles that employ a tapered geometry. The projector optionally 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/or change the depth and roll when the projector is configured as a tow body. A plurality of such projectors can be configured in an array. An umbilical can connect the projectors to a vessel, transmit electrical power and compressed gas to each array element and/or provide a data transmission medium between the projector and the vessel.

摘要： A method for estimating a tilt angle β(t) of at least one given particle motion sensor nearly collocated, in a multi-sensor streamer for seismic prospection, with a pressure sensor. The given particle motion sensor has two orthogonal sensing axes Y and Z in a plane orthogonal to a longitudinal axis of the streamer. The tilt angle is formed by the Z sensing axis and a reference vertical axis Z0. The method comprises, for the given particle motion sensor, a step of computing a first estimate β0 of the tilt angle, comprising, while the streamer is being towed: obtaining (41) first data measured by the pressure sensor nearly collocated with the given particle motion sensor; obtaining (42) second and third data measured by the given particle motion sensor along the sensing axes Y and Z respectively; for at least two values of a rotation angle θ, rotating (45) the second and third data by the rotation angle θ, to obtain rotated second and third data; and computing (46-410) a particular value θmax among the at least two values of the rotation angle, which maximizes, over at least one frequency, a coherence function between the first data and the rotated third data, or between the first data and velocity data resulting from an integration of the rotated third data, the particular value θmax being equal to said first estimate β0. Step of computing a first estimate β0 of said tilt angle is processed independently of any seismic signal.
