(Phys.org) —Radar systems today depend increasingly on phased-array antennas, an advanced design in which extensive grids of solid state components direct signal beams electronically. Phased array technology is replacing traditional electro-mechanical radar antennas – the familiar rotating dish that goes back many decades – because stationary solid state electronics are faster, more precise and more reliable than moving mechanical parts.
