In aperture synthesis measurements in Radioastronomy, the measurement set is frequently three-dimensional (in space) and therefore cannot be simply represented in two-dimensions. As a result, the point spread function for the instrument varies as a function of direction. This has been considered in recent publications in relation to digital data processing and some of the features of the three-dimensional problem, and methods for implementing the computation using one- or two-dimensional transforms is presented.
