Beamspace adaptive beamforming for ultrasound imaging
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2009Applying the Capon adaptive beamformer in medical ultrasound imaging results in enhanced resolution by improving the interference-suppressing capabilities of the array. This improvement comes at the expense of an increased computational complexity. We have investigated the application of a beamspace adaptive beamformer for medical ultrasound imaging ...

Sonar (sound navigation ranging) is an apparatus that detects the presence and location of submerged objects (as a submarine) by means of sonic waves reflected back from or produced by an object.

Deep Learning for Fast Adaptive Beamforming
ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019The real-time nature that makes diagnostic ultrasonography so appealing to clinicians imposes strong constraints on the computational complexity of image reconstruction algorithms. As such, these typically rely on traditional delay-and-sum beamforming, a low-complexity approach that unfortunately comes at the cost of reduced image quality as compared ...

Symmetrical Component Adaptive Beamforming
The Journal of the Acoustical Society of America, 1968The theory of symmetrical components, long used in connection with fault-current analyses of multiphase power-distribution systems, has been applied to the problem of adaptive beamforming with the result that the response of a spatially diverse array of sensors can be made virtually free of the effects of the stationary part of the surrounding noise ...

Universal switching adaptive beamforming
The Journal of the Acoustical Society of AmericaAn adaptive beamformer may be thought of as trading white noise gain for interferer suppression. The beamformer can respond to changing environmental statistics through updates to the sample covariance matrix. In time-varying environments, adaptive beamformers are frequently used with pre-determined sliding windows or forgetting factors for such sample

Systolic Array Adaptive Beamforming
1987Abstract : A computing architecture which reflects the specific requirements of an optimum adaptive space-time array processor is discussed. Specifically, a frequency domain implementation of the minimum variance distortionless response (MVDR) beamformer is described.
