Attaining Phase Coherency for Multiple Data-Converter Systems (.PDF Download)

Electronic beamsteering is a fairly old technology and dates back to around 1905, when Karl Braun demonstrated phased-array transmission of radio waves to improve directionality. The same principles were used on early radar systems during the Second World War. In principle, phased-array systems employ a series of equally spaced antennas, typically a quarter wavelength apart, that use constructive and destructive interference of the transmitted (or received) signal, resulting in a directional
