摘要

射电天文学面临着从单个天线元件到信号处理站的信号传输的非常具体的、系统的和环境的挑战。在这里，我们介绍了如何通过模拟光链路来满足这些要求，特别是对于平方公里阵列(SKA)的低频接收器，它将成为世界上最大的射电望远镜。它将由超过10万个单独的天线组成，这些天线需要在长达10公里的距离上连接起来。

Analog Optical RF-Links for Large Radio Telescopes

Radio astronomy faces very specific, systematic and environmental challenges regarding signal transport from individual antenna elements to the signal processing station. Here we present how with analog optical links these requirements can be met, specifically for the low-frequency receiver of the Square Kilometre Array (SKA), which will be the world's largest radio telescope when finished. It will comprise more than 100'000 individual antennas, which need to be connected over a distance of up to 10 kilometers.
