[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.
