Beamforming

Beamforming or spatial filtering is a signal processing technique used in sensor arrays for directional signal transmission or reception. 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. Beamforming can be used at both the transmitting and receiving ends in order to achieve spatial selectivity. The improvement compared with omnidirectional reception/transmission is known as the directivity of the array. Beamforming can be used for radio or sound waves. It has found numerous applications in radar, sonar, seismology, wireless communications, radio astronomy, acoustics and biomedicine. Adaptive beamforming is used to detect and estimate the signal of interest at the output of a sensor array by means of optimal (e.g. least-squares) spatial filtering and interference rejection.

An introduction to Beamforming

This video talks about how we actually have more control over the shape of the beam than just adding additional elements or adjusting the position and orientation of the elements. We can also adjust the gain of the signal to each element and apply phase unevenly to each element, and that

Beamforming by Phased Array Antennas 📡 - A visual example

In this second video of the series on beamforming, we show the time domain wave propagation for two phased array antennas at different phase differences. Thanks to the constructive and destructive interferences, the main beam of the wave is steered towards angle of interest. See also: M

Why multichannel beamforming is useful for wireless communication

Wireless communication systems like 5G and WiFi usually have to serve many users simultaneously and they have to deal with multiple paths between two radios when operating in a scattering rich environment. This video covers how multichannel beamforming and spatial diversity is used to over

Phased Array Antenna Beam Steering Animation (Beamforming visualized)

Beam steering via phased antenna arrays is demonstrated. The arrays are composed of 7 point sources uniformly spaced in a linear fashion (uniform linear array (ULA). The antenna separation is denoted by the parameter d. When the separation is smaller, the directivity of the array is narro

Antenna Array Beamforming using 2 Elements - Constructive and Destructive Interference 📡 #antenna

Here we show beamforming patterns generated by two dipole antenna elements fed with difference phase differences and separated by a certain distance. By changing the phase difference as well as the separation distance, the propagation pattern can be significantly changed. The constructive

What Are Phased Arrays?

This video introduces the concept of phased arrays. An array refers to multiple sensors, arranged in some configuration, that act together to produce a desired sensor pattern. With a phased array, we can electronically steer that pattern without having to physically move the array simply b
