摘要： A method and system for locating the position of a source that emits a rotating magnetic field. Three or more receivers are deployed or positioned in known position relative to each other, which may be along a common axis in some cases. Phase differences between the magnetic fields measured by the receivers are detected. The phase shifts are used to determine the location of the source. With three receivers, a range and bearing angle relative to a middle receiver may be determined. With five or more receivers, a range and two bearing angles may be determined, thereby providing a three-dimensional position.

摘要： A method and towed sonic array system for defocusing the beampattern of the towed sonic array. The method includes determining an amplitude adjustment and a phase adjustment for each of the sonic projectors; and driving each of the sonic projectors with a drive signal modified by the amplitude adjustment and the phase adjustment for that sonic projector. The amplitude adjustment and phase adjustment for each of the sonic projectors are, at least in part, based upon the distance from that sonic projector to a virtual source. The location of the virtual source may be selected so as to achieve different beampatterns, including wide-sector beams and, in at least one case, a near-omni-directional beampattern. The drive signal may include multiple frequency components, in which case the method may be used to find a set of beamformer coefficients for each of the frequency components and an inverse transform may be used to realize a defocused driving signal.
