互耦条件下相控阵天线的配相校准技术 ABSTRACT ABSTRACT As the continuous update and development of radar, navigation and satellite communication system, phased array antenna is widely used in various military and civil electronic equipments due to its high gain, multi-beam forming ability and fast ...
本文在分析相控阵天线近场特性的基础上,根据信号子空间的基本理论,结合模拟退火算法,提出了一种利用近场辅助源估计相控阵天线互耦系数的方法.大量的计算机仿真结果表明,本方法使用校准源少,校准源到天线阵距离近,算法稳健,即使在雷达工作、并且存在其它未知信号时,也能准确估计出天线阵的互耦系数. Full-Text Contact...
