摘　　要：从无线电高度表工作原理的分析与研究出发,提出了基于虚拟仪器技术和I/Q调制器的无线电高度表动态测试系统的总体设计,同时对测试数据的处理理论进行了一定的分析和研究。结合高度表测试实例,采用基于数据采集卡的虚拟仪器方式完成了系统的构建。This paper analyzes the working mechanism of aerodynamic missile-borne radio altimetre and puts forward a new design for the radio altimetre based on virtual instrument and I/Q modulator. By some instances of radio altimetre, dynamic test system is designed. Though the practice project, this new system actually can simulate the dynamic working progress of radio altimetre all-sidedly, and check out fault of altimetre as quickly as possible.
