<p>Disclosed are array antenna systems for radiating wave energy signals in a Doppler coded pattern. These systems include an array of antenna elements, means for supplying wave energy signals to the elements and means for controlling the phase of the wave energy signals supplied so that wave energy signals radiated by adjacent pairs of elements have a direction of phase reinforcement which is constantly changing and no two pairs of elements in the array have the same direction of phase reinforcement at the same instant of time. The invention may be applied to many array configurations including circular, cylindrical, linear and planar arrays.</p> |
