The authors extend DFT (discrete Fourier transform) processing of phased arrays operating in sequential mode to primely spaced arrays. Advantages include: one can use elements of different sizes to improve the gain; the information sequence is smaller and needs less memory storage; lower sidelobe levels are achieved without the need of tapering hardware; and fewer elements can be used without degrading the array pattern. Examples validate and demonstrate the technique. The approach is demonstrated for both linear and rectangular arrays
