  2. Synthetic aperture ultrasound - Wikipedia

    en.wikipedia.org/wiki/Synthetic_Aperture_Ultrasound

    The second stage beamformer creates a set of high resolution image points by combining information from multiple focused scan lines acquired in the first stage. For a linear array transducer with multiple elements, the lateral resolution of sequential beamforming SAU can be made more range independent and significantly improved compared to ...

  3. Beamforming - Wikipedia

    en.wikipedia.org/wiki/Beamforming

    Beamforming or spatial filtering is a signal processing technique used in sensor arrays for directional signal transmission or reception. [1] This is achieved by combining elements in an antenna array in such a way that signals at particular angles experience constructive interference while others experience destructive interference.

  4. Phased array - Wikipedia

    en.wikipedia.org/wiki/Phased_array

    Time domain beamformer works by introducing time delays. The basic operation is called "delay and sum". It delays the incoming signal from each array element by a certain amount of time, and then adds them together. A Butler matrix allows several beams to be formed simultaneously, or one beam to be scanned through an arc. The most common kind ...

    Beamforming is one kind of filtering that can be applied to isolate signal components that are propagating in a particular direction.. In the picture is the most simple beamformer-the weighted delay-and-sum beamformer, which can be accomplished by an array of receivers or sensors. Every triangle is a sensor to sample in spatial domain.

  7. Digital antenna array - Wikipedia

    Transposed Block Face-splitting product in the model of a Multi-Face radar with DAA, proposed by V. Slyusar in 1996 [5]. The main approach to digital signal processing in DAA is the "digital beamforming" after Analog-to-digital converters (ADC) of receiver channels or before Digital-to-analog converters (DAC) by transmission.
