中国碟形验证天线（DVA-C）是一个正在建造的原型，以最大限度地满足平方公里阵列科学目标的要求。在本文中，DVA-C的光学设计的细节，包括盘光学，和估计的性能。虽然DVA-C是为最佳性能而设计的，但它也有可能用于相控阵馈电。因此，DVA-C的多波束性能进行了分析。
The Dish Verification Antenna China (DVA-C) is a prototype being built to farthest meet the requirements from the Square Kilometre Array scientific goals. In this paper, the details of the optical design of the DVA-C are presented, including the dish optics, and the estimated performance. Although the DVA-C is designed for optimal performance on bore sight, it is potentially employed for phased array feeds. Hence the multi-beam performance of the DVA-C is also analyzed.
