Electronic Compensation for Reflector Surface Distortion to Improve Radiation Pattern Characteristics of Antennas

摘要

A simple procedure is described for determining the excitation coefficients of an array feed which compensates for the surface distortion of a reflector antenna to improve the radiation pattern in such a way as to approximate the performance of the undistorted antenna. A computer simulation for a practical feed array is presented as an example of compensation for the distortion of an actual antenna.
