摘　　要：中国频谱日像仪(Chinese Spectral Radioheliograph,CSRH)一期工程包括40面天线(400 MHz～2 GHz)组成的天线阵,二期工程包括60面天线(2～15 GHz)。天线统一控制包括天线指向调整、目标源跟踪、射电定标等。无论何种情况,所有的天线均需统一协调工作。对CSRH天线阵列整体控制进行了研究,提出了一种基于以太网的CSRH天线阵控制方案,并对可能遇到的关键问题进行分析。The Chinese Spectral Radioheliograph（CSRH） is a radio synthesis imaging telescope dedicated to observe the sun,working on multiple frequencies in a centimeter-to-decimeter range.The CSRH-I system includes an antenna array composed of 40 antenna elements（400MHz-2GHz）,and the CSRH-II has 60 antennas（2GHz-15GHz）.All of the antennas must be under unified control in many working modes such as adjusting pointing of each antenna,tracking specified sources,and system calibration.In this paper we explore a design of a unified-control system based on Ethernet for the CSRH antenna arrays.A Distributed Control System（DCS） is preferred for the design given the required individual or unified control of the antennas.From the comparison of an Ethernet to field buses in various aspects,we think an Ethernet can meet the requirements of the CSRH antenna control system.We finally analyze some key issues to be probably encountered in practice.
