平方公里阵列（SKA）目前已进入前期建设阶段，包括中国在内的约20个国家的上百家机构已参与其关键技术开发。中国碟形验证天线（DVA-C）是为了最大程度地满足SKA科学目标的要求而建造的原型，具有独特的蒙皮和肋结构单片面板反射器。本文介绍了DVA-C的设计，包括光学设计、碟形结构和伺服系统。提供了测量的电磁和结构性能以及初步观测结果。
The Square Kilometer Array (SKA) has now entered into the pre-construction phase, A hundred of institutes in about 20 countries including China have been involved in its key technology development. The Dish Verification Antenna China (DVA-C) is a prototype being built to farthest meet the requirements from the SKA scientific goals, with unique skin-and-rib structure single-piece panel reflectors. In this paper, design of DVA-C is presented, including optical design, dish structure, and servo. The measured electromagnetic and structural performances, as well as preliminary observational results are provided.
