摘要
传统的相位差测量系统,因其工作的频段窄,测量精度低,已不能满足现代相控阵技术的要求。本文提出了一种基于虚拟仪器的相位差测量系统的设计方法,重点阐述了系统的工作原理,最后给出了测试记录和结论。
With its narrow operating frequency scope and low measuring precision ,traditional phase difference measuring system can' t satisfy the requirement of modern phase array technology . This paper presents a phase difference measuring system based on virtual instrument designing method , with emphasis on the system operating principle . The testing record and result is given at last.
