<p>An array antenna system (40) includes an antenna (42) having a plurality of radiators (44) generating a set of beams (48). The axes of the beams (48) are spaced apart from each other allowing the respective beams (48) to illuminate separate areas of a receiving region. The antenna system (40) includes offset means coupled to the antenna (42) for applying a sequence of positional offsets to the set of beams (48) wherein, for any one beam (48), the positional offsets drive the beam (48) around a central location (50) of the beam (48) to illuminate locations between said separate areas. <IMAGE></p> |
