Abstract

This paper presents a methodology to estimate Array Fed Reflector (AFR) farfield patterns through interpolation using a small set of computed points. A technique to unwrap the phase pattern is introduced, which is essential to obtain valid results when interpolation is applied. This methodology reduces the computational effort required to calculate AFR beams in a multibeam scenario with a large number of beams, which is the case for future Very High Throughput Satellite (VHTS) systems. An efficient and accurate tool that predicts the performance of these systems is a key step in the design and optimization of the satellite payload.
