Abstract
A method is described for digital correlation of very wideband signals from a radio interferometer. The intent of the method is to achieve maximum spectral resolution at minimum cost. Data are digi- tally ltered and decimated into lower rate sub-bands which are sepa- rately cross-correlated and integrated before being seamlessly stitched together to yield the nal wideband spectrum. Simulation results compare this method with a full band correlator.Keywords
