摘要

讨论了用于高质量海洋测量的新一代星载辐射计系统。用焦平面阵列代替传统的喇叭作为天线馈源。天线波束是由许多小型天线元件的输出叠加而成，从而提供了无与伦比的天线波束。这解决了传统的极化纯度和土地/海洋污染问题。该概念要求卫星上有许多微波接收器和快速模数转换器以及快速数字信号处理。对此进行了讨论，并提供了资源预算，特别是与电力有关的预算。

Ultra-High Performance C & L-Band Radiometer System for Future Spaceborne Ocean Missions

A next generation spaceborne radiometer system for hi-quality ocean measurements is discussed. Instead of a classical horn, a focal plane array is used as antenna feed. The antenna beam is created by adding the outputs from many small antenna elements, thus providing an antenna beam of unsurpassed quality. This solves the classical polarization purity and land / sea contamination issues. The concept requires many microwave receivers and fast analog-to-digital converters as well as fast digital signal processing on-board the satellite. This is discussed, and resource budgets, especially concerning power, are provided.
