Abstract
Arrays with good autocorrelation functions are required for coded
aperture imaging. A generalized folding procedure is derived that permits the
construction of arrays with good correlation properties from well correlating
sequences for many array sizes. This synthesis method is applied to the
construction of approximately square binary arrays with a single zero element
and perfect odd-periodic autocorrelation functions. In addition, new binary
arrays with constant sidelobes of their periodic autocorrelation functions
(uniformly redundant arrays) can be generated with the generalized folding
method.
