SYNTHESIS OF BINARY ARRAYS WITH PERFECT CORRELATION-PROPERTIES - CODED-APERTURE IMAGING

A new method for the synthesis of binary arrays which have perfect cro ss-correlation properties is presented. The arrays, which are discusse d with an emphasis on coded aperture imaging, may also be of use in a number of other applications, including signal processing, telecommuni cations and radio antenna design. The new coded aperture configuration s which are made available offer a wider choice of possible aperture p arameters, and conveniently fill a gap in the system parameters that a re currently available. The increased freedom of system choice, which can be made for both one- and two-dimensional systems, includes the si ze of the aperture array and its throughput value. The new two-dimensi onal apertures have the further advantage of being fully self-supporti ng.
