Beam Forming Designer

beamforming.jpg beamforminggraph.jpg


Beam-former algorithm with fractional delay combines signals in a manner which increases the signal strength to/from a chosen direction. Signals to/from other directions are combined in a benign or destructive manner, resulting in degradation of the signal to/from the undesired direction.
