摘要
文章以中国空间技术研究院紧缩场测试系统的组成和特点为例,分析介绍了紧缩场测试误差的来源、测试设备必要的升级改造和测试软件的更新应用。通过将测试理论知识应用于测试工程实际,可有效去除由于测试场非理想因素引入的各类测试误差,获得更接近天线实际性能的测试结果;同时有效分析处理测试数据,简化实际测试工作,提高测试效率。
This paper describes the components and features of the antenna measurement system for the compact test range built in China Academy of Space Technology by analyzing the source of measurement errors,the necessity for upgrading the measuring apparatus,and the new application of software for measurement.It has been proved in practice that through theoretically analyzing the test data in the real compact range,errors resulted from nonideal factors can be eliminated,and accurate results can be obtained while ignoring some unimportant factors to simplify the test practices.
