摘　　要：随着天线测试技术的发展,近场测量已成为当今高性能雷达天线,特别是有源相控阵雷达天线研制的必要手段。文中给出了对于大型平面近场测量系统中分布式射频子系统的布置与设计要求。功率预算的结果验证了这种设计可以满足高精度、大扫描行程天线的测试要求。With the development of the antenna measurements technology,near field measurements become the indispensable approach to research on high performance radar antenna,especially on the active phased array antenna.The paper presents the system arrangements and design requirements of the distributed RF systems which are applied to the large planar near field measurements systems.The results of the power budget computation demonstrate that the system design can satisfy these requirements of antenna measurements,which need high precision and large scan areas.
