米波警戒雷达天线小型化研究

Study on Miniaturization of the Meter Wave Early Warning Radar Array

分析了单元间距较大的小型天线阵的基本特性 ,探讨了这种天线阵的设计方法。设计了一个小型大间距八木阵 ,试验结果表明 ,这种天线阵增益高、波瓣性能好 ,是米波警戒雷达天线小型化的有效途径之一。

This paper analyses the basic characteristics of the miniaturized array with large elements distance, and discusses the design of the array. A Yagi antenna array was designed, and the test results show the array has better performances. By the design method, the meter wave warning radar array can be miniaturized efficiently.
