某国外大型天线测试系统国产化改造研究

Research for the local modification to an imported large-sized antenna test system

该文介绍了从以色列引进的大型天线远场测试系统的组成、应用、工作原理、工作特点。针对原系统的功率设计余量不够、可维修性差等缺点,根据系统性能指标及用户要求重新设计制作功率控制单元,通过工控计算机运行用C语言编写的接口控制软件,实现与原系统兼容,从而使新的功率控制单元嵌入到原系统,最终实现原系统的所有功能。改造后的系统经过验收和实际使用,证明改造后的系统在操作性、维修性、可靠性、安全性方面都有了加强,满足系统指标及用户要求。

The article describes the composition, application,working principle, and working features of a large antenna far-field measurement system imported from Israel. In order to overcoming the shortages of the original system such as insufficient margin for designed power and difficult maintenance etc, the author redesigns and makes power control unit based on the system＇s performance index and customers＇requirement, Through the software compiled by C programming language for interface control that run on a industry-control computer,the new power control unit is compatible with the original system and can be embeded in it. So all the functions of the original system have been realized finally. It is proved after acceptance test and practical application that the new system has been improved in operation, maintenance, dependability, and safety. It could meet the system performance index and customers＇requirement, and has certain economic value.
