基于虚拟仪器技术的雷达测试系统研究

摘要

介绍了基于GPIB虚拟仪器技术的雷达自动测试系统的硬件构成和软件设计方法.通过对虚拟仪器技术的深入研究,重点论述了虚拟仪器技术的特点及其对本系统的有力支持,同时对雷达和方向图、差方向图、雷达轴比以及增益等雷达分系统性能测试方法也进行了详细的论述,并通过几个典型的软件设计模型分析了影响测试结果可靠性的诸多因素和环节.%The hardware structure and software design method of the radar auto-test system based on GPIB virtual instrument technique are.ntroduccd. Through the further research on the virtual instrument technique, whose characteristics and a powerful support for the test system are discussed emphatically; at the same time, the performance test methods for radar subsystem such as dB-radiation pattern, difference radiation pattern, radar' s axis-ratio and gain and so on are presented.Many factors that influence the reliability of the Internet applications are analyzed by several typical software dcsign models.
