【摘要】：作为雷达系统不可或缺的组成部分,天线近年来取得了突飞猛进的发展。其中相控阵天线因其具有扫描速度快、波束控制灵活、多目标搜索跟踪、自适应和抗干扰能力强等优势,在军用目标搜索指示、炮位侦校和机载火控等领域得到越来越广泛的应用。在相控阵天线技术发展的引领下,天线的测试技术也必须不断发展,以适应相控阵天线不断增大的体积和不断增加的通道数的需要。本文论述了一种以PXI架构(PCI extensions for Instrumentation,即PCI技术在仪器方面的扩展)的模块化仪器为基础的天线测试系统设计,搭建了系统硬件,并在LabVIEW平台上完成了相关软件的设计,从而实现了天线远场的幅度和相位测量。本文应用最新的测试技术构建了准确、经济、便携的天线测试系统,经实验测试,系统的硬件构成和软件设计能够满足预期要求。论文主要包括以下几部分研究内容:第一章首先介绍了本系统的研究背景,对国内外天线测试系统的研究现状进行了分析;第二章研究了天线测试的基础理论,为选择测量方法做出准备;第三章根据对基础理论的分析,设计出天线测试系统的整体方案,给出系统各个组成部分的需求和实现方式;第四章给出天线测试系统硬件部分具体的型号选择和技术指标,完成硬件平台的构建;第五章设计出天线测试系统的控制软件,实现对硬件平台的控制和测量结果的分析;第六章会在实验室和实际测试场分别对测试系统的性能进行验证;最后会对全文进行进行总结并对今后的工作进行展望。
[Abstract]:As an indispensable part of radar system, antenna has made rapid development in recent years. The phased array antenna has the advantages of high scanning speed, flexible beam control, multi-target search and tracking, adaptive and anti-jamming ability. Gun position detection and calibration and airborne fire control are more and more widely used. With the development of phased array antenna technology, the antenna testing technology must be continuously developed to meet the needs of increasing volume and increasing number of channels of phased array antenna. In this paper, the design of an antenna testing system based on PXI architecture (PCI extensions for Instrumentation, (the extension of PCI technology in instrument) is described. The hardware of the system is built, and the related software is designed on the platform of LabVIEW. Thus the measurement of the amplitude and phase of the antenna far field is realized. In this paper, an accurate, economical and portable antenna testing system is constructed by using the latest testing technology. The hardware structure and software design of the system can meet the expected requirements. The thesis mainly includes the following parts: the first chapter introduces the research background of this system, and analyzes the current situation of antenna testing system at home and abroad. Chapter 2 studies the basic theory of antenna testing. In the third chapter, according to the analysis of the basic theory, the whole scheme of antenna test system is designed, and the requirements and realization of each component of the system are given. The fourth chapter gives the hardware model selection and technical index of the antenna test system, completes the construction of the hardware platform, in the fifth chapter, designs the control software of the antenna test system, realizes the control of the hardware platform and the analysis of the measurement results. The sixth chapter verifies the performance of the test system in the laboratory and the actual test field, and finally summarizes the whole paper and looks forward to the future work.
