Abstract: | Formulae are given for the aperture plane phase errors which are incurred in near-field radioholography of reflector antennas when a simple Fresnel correction is used. Approximate analytic expressions are derived for circular data windows and antennas with parabolic illumination taper. Infocus and defocused cases are treated. Numerical simulations are used for estimating errors for square data windows |
