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

A new method for the synthesis of binary arrays which have perfect cross-correlation properties is presented. The arrays, which are discussed with an emphasis on coded aperture imaging, may also be of use in a number of other applications, including signal processing, telecommunications and radio antenna design. The new coded aperture configurations which are made available offer a wider choice of possible aperture parameters, and conveniently fill a gap in the system parameters that are currently available. The increased freedom of system choice, which can be made for both one- and two-dimensional systems, includes the size of the aperture array and its throughput value. The new two-dimensional apertures have the further advantage of being fully self-supporting.
