摘要

平方公里阵列(SKA)需要大约2000+ 15米的反射天线来实现一个收集面积相当于100万平方米的射电望远镜。这些天线的成本和性能对望远镜有很大的影响。在本文中，我们报告了开发SKA碟形验证天线-1的结果-一种新型的15m双偏置格里高利设计，使用由碳增强塑料制成的单片边缘支撑主反射镜和二次反射镜，具有成本和性能优势。

Development of the Dish Verification antenna-1 for the Square Kilometre Array

The Square Kilometre Array (SKA) requires roughly 2000+ 15m reflector antennas to implement a radio telescope with a collecting area equivalent to 1 million square metres. The cost and performance of these antennas impact the telescope significantly. In this paper we report the results of developing the SKA Dish Verification Antenna-1 - a novel 15m dual offset Gregorian design using single-piece rim supported primary and secondary reflectors made of carbon reinforced plastic which yield cost and performance advantages.
