本文讨论了机载和星载雷达系统天线使用的全重叠子阵方案。说明这种子阵系统的天线波辦旁辦低,能宽角扫描并且具有宽频带使用的潜力。说明如何通过对多波束馈电系统输出端口的信号进行处理在主辦和旁辦内得到零点。文章还说明了重叠子阵中如何用相位中心偏移技术(DPCA)来对消杂波干扰。
This article discusses the fully overlapping subarray schemes used by the airborne and spaceborne radar system antennas. Description of this sub-array antenna system to do Office next to do low, wide-angle scan and has the potential to use broadband. Explains how to get zero points in the host and by-pass by processing the signals at the output ports of the multi-beam feed system. The article also shows how to use phase center shift technique (DPCA) to eliminate clutter in overlapping subarrays.
