摘要
电扫描是相控阵雷达的一大优点,它克服了普通雷达机械扫描时速度的限制。一个性能优良的相控阵天线不仅要有好的辐射单元,与之相匹配的馈电网络也是至关重要的。数控移相器是相控阵天线馈电网络的核心元件,主要用来控制天线单元和子阵福射信号的相位,使得辐射波束能够进行扫描,另外它也用于数字通信,作为调相器,是相控阵组件的核心组成部分,成本、性能直接影响着系统的造价和性能。本文主要通过测试数据阐述集成数控移相器在相控阵雷达中的重要性。
Electrical scanning is one of the great advantages of phased array radar, which overcomes the speed limit of mechanical scanning in ordinary radar. Excellent performance of phased array antenna should have not only depend on good radiation unit, matching with the feeding network is crucial too. Digital phase shifter is the core element in phased array antenna feeding network, mainly used for antenna element radiation signal's phase control, so that the radiation beam can be scanned. And it is also used in digital communication as phase modulator, which is the core part of the phased array assembly,its cost and performance affects the cost and performance of the system directly. This paper mainly used the test data,expounding the importance of integrated digital control phase shifter in phased array radar.
