X波段双极化有源相控阵天线的设计

机载或星载X波段有源相控阵雷达系统具有很高的分辨率，由于雷达系统使用了大量双极化子阵组成的有源相控阵天线（俯仰面和方位面均需扫描），频率的升高使得子阵馈线网络的可用面积受到了很大的限制。本文着重论述了有源相控阵天线中的双极化阵设计，提出了一系列解决方法，进而叙述了整个天线阵的设计。

Design of X-Band Dual-polarization Active Phased Array Antenna

The X band active phased array radar (APAR) has high resolution. But the available area of feed network in the subarray is restricted badly, because the APAR uses the active phased array antenna (APAA) which is constituted of a great deal of dual polarization subarrays (beam steering at both azimuth and elevation planes). This paper emphasizes on the design of dual polarization subarrays and presents a serial of solution methods, then narrates the design of the array.
