| Summary: | Scalar field theory has been used to develop an accurate beam model for use with the National Radio Astronomy Observatory 91 meter radio telescope and the 6 cm dual feed system. The theoretical beam model was calibrated, to an accuracy of 3% of the beam peak, with a small sample of radio point sources within the declination range 23° ≤ δ ≤ 62°. The new beam model is shown to be effective in deconvolving differential beam maps, to a dynamic range of 30:1, by a maximum entropy deconvolution method. === Science, Faculty of === Physics and Astronomy, Department of === Graduate
