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 digitally filtered and decimated into lower rate sub-bands which are separately cross-correlated and integrated before being seamlessly stitched together to yield the wideband spectrum. Simulation results are presented to enable a comparison to be made of this method with results obtained using a full band correlator.
