摘要：

This paper presents an efficient methodology for the estimation of multibeam antenna system performance for satellite applications with a large number of beams typically required in very high throughput satellite systems. A typical antenna system composed of four offset reflectors with feed systems in a single-feed-per-beam configuration is used to achieve full Earth coverage. Acceleration techniques are applied to estimate farfield patterns for each beam with the aim of finding a trade-off between accuracy and computation time on system level metrics, such as aggregate gain and C/I. The software obtained as part of this work is of interest for payload trade-offs and parametric studies.
