Phased Array Weighting in Antenna Arrays If a plane wave is incident upon an antenna array (Figure 1), the phase of the signal at the antennas will be a function of the angle of arrival of the plane wave. If the signals are then added together, they may add constructively or destructively, depending on the phases. Modern warfare weird guns
