  • Patent number: 11143774
    Abstract: Simultaneous sources are separated with a deblending method wherein the fullband data deblended on a source-by-source basis. The fullband data is first decomposed into multiple subbands, and then a non-equispaced subband Radon transform is used to transform the decomposed data into the Radon domain. The deblending process is solved subband by subband by minimising a nonlinear objective function. The solution of the nonlinear objective function is found using a multi-step procedure.

  • Patent number: 10996332
    Abstract: Systems and methods are disclosed for performing imaging with a crossed-electrode ultrasound transducer array, where ultrasound transducer array is configured for focusing in one direction via conventional time-delay phased array beamforming, and for focusing in a second direction via a Fresnel aperture formed via the application of bias voltages. The ultrasound transducer array connections are switched between transmit and receive operations, such that the Fresnel aperture is generated in the first direction upon transmit, and in the second direction upon receive. One or both of the transmit Fresnel aperture and the receive Fresnel aperture are configured as a set of delay-corrected Fresnel sub-apertures, where the delay associated with each Fresnel sub-aperture is selected to compensate for variations in path lengths between the Fresnel sub-apertures and the focal point.

  • Patent number: 10877151
    Abstract: A small aperture acoustic velocity sensor and a method for velocity measurement are disclosed. In one aspect, the disclosed technology uses spatially-shifted sub-arrays for projection and/or hydrophone receipt and cross-correlation of successive pulses to improve correlation and reduce bias. The spatial shift can be created physically by selection of groups of elements or virtually by weighting the contributions of fixed sub-arrays. Spatial modulation can be used to form a projected signal and measured spatial phase of slope across the set of sub-arrays allows correction of both long- and short-term errors. The disclosed technology uses spatial and/or temporal interpolation.
