Spectral-bandwidth constraints to ensure controlled amounts of redundancy are established for a class of two-dimensional partially redundant arrays (PRA’s). In the IR, where speckle statistics are poor, the telescope-atmosphere modulation transfer function is determined solely by the PRA geometry. Signal-to-noise-ratio estimates, an optimum aperture criterion, and a six-element PRA example are presented.
