Calculation of the secondary-radiation pattern for a paraboloid reflector with a given illumination function and feed position
A computer program is described for the calculation of the near-axis secondary-radiation pattern of a parabolic reflector. The program has been devised for a laterally or axially displaced feed, in particular a log-periodic dipole array. The illumination-function data are input in the form of radiation-pattern co-ordinates of the feed aerial.
