Claim:
1. A method of controlling sidelobe distribution in an active electronically steered array including a plurality of radiators, the method comprising: electronically reshaping an aperture of the array to control the sidelobe distribution to reduce sidelobes over a selected region of a coverage volume of the array at least in part by deactivating a subset of the plurality of radiators at an edge discontinuity of the array to cause at least some of the sidelobes to move off a principal plane of the array and reduce the sidelobes over the selected region of coverage; applying a uniform illumination distribution to the plurality of radiators corresponding to the reshaped aperture; and dynamically reconfiguring the reshaped aperture between a right parallelogram-shaped aperture and a left parallelogram-shaped aperture responsive to movement of the array.
