Abstract: A method of controlling sidelobe distribution in an active electronically steered array, including electronically reshaping the array aperture so as to reduce sidelobes over a selected region of a coverage volume of the array. In one example, reshaping of the aperture is achieved by electronically turning on and/or off selected radiators in the array to vary the angle of edge discontinuities of the aperture, and thereby move the main sidelobes off the principal plane(s) of operation of the array.
