本文提出了一些技术来估计多波束阵馈反射面天线的波束形成系数，成像几何产生大量的波束，非常高通量卫星（VHTS）系统的兴趣。这些技术的比较研究，提出了使用天线配置设计，以满足VHTS系统的要求，全地球覆盖。在不同的情况下，也考虑了从元件激励中去除幅度信息的影响。载波干扰比（C / I）方面的数值结果报告比较不同的情况下，在定义的覆盖范围内的卫星天线系统的性能和技术的影响。
This paper presents some techniques to estimate beamforming coefficients in multibeam array fed reflector an-tennas with an imaging geometry generating a large number of beams, of interest for very high throughput satellite (VHTS) systems. A comparative study of these techniques is proposed using an antenna configuration designed to meet VHTS system requirements with full earth coverage. The impact of removing the amplitude information from the elements excitations is also considered with different scenarios. Numerical results in terms of carrier-to-interference (C / I) are reported to compare the impact of the different scenarios and techniques on the performance of the satellite antenna system over the defined coverage.
