摘要

本文分析了具有波束形成的数字辐射计所需的比特数，重点分析了积分时间以及信号质量标准差与ADC转换窗口之间的关系。结果是从一个特定的拓扑(paul - seosat /INGENIO[1])获得的，但可以应用于任何数字辐射计和未来的合成孔径辐射计任务。

The impact of the number of bits in digital beamforming real aperture and synthetic aperture radiometers

This work analyzes the number of bits required in a digital radiometer with beamforming focusing on the integration time and on the relationship between the signalpsilas standard deviation and the ADC conversion window. Results are obtained from a particular topology (PAU-SEOSAT/INGENIO [1]), but can be applied to any digital radiometer and to future synthetic aperture radiometers missions.
