脉冲雷达高度表通用测试设备的设计

Design of universal test equipment of pulse radar altimeter

摘要:

利用虚拟仪器技术可提高测试系统的灵活性和可扩展性。文中介绍了一种脉冲雷达高度表的通用测试设备的设计方法，以计算机和标准仪器为硬件平台，通过Visual C++调用LabVIEW编写的控制标准仪器的动态库函数，可以对脉冲雷达高度表的工作电压、发射频率、接收频率、动作灵敏度、发射功率等参数进行测量。通过Visual C++编写的界面程序可直接显示、打印、存储测量结果，可供以后查询。利用参数化设计技术和数据库建模知识，通过在参数表中增加记录和升级动态库函数可以方便地用该测试设备测试其他的脉冲雷达高度表。

Abstract:

Virtual instrument technology can improve flexibility and expansibility of test system. A design method of universal test equipment for pulse radar altimeter is introduced in this paper. Based on computer and standard instruments，by using Dynamic Link Library(DLL) of standard instruments control built by LabVIEW via Visual C++, the parameters of pulse radar altimeter such as working voltage，transmitting frequency，receiving frequency，movement sensitivity and transmitting power can be tested，displayed，printed and stored. The test results can be queried in the future. By increasing notes in parameter list and upgrading DLL，it is convenient to measure other types of pulse radar altimeter with this test equipment using parametric design and database modeling technology.
