一种新型北斗二代抗干扰零相位天线阵

A new Beidou two generation anti jamming zero phase antenna array

在同一个大地板上,构造抗干扰天线阵列兼零相位中心天线是一个新颖并有意义的难题。零相位天线要求天线阵子下面的接地板完全地称,而抗干扰天线阵则要求每个阵元以接地板为中心,均匀旋转分布。因此,本文提出一种新颖的做法,直接利用四个抗干扰阵元合成一个"虚拟"的零相位阵元,使天线阵能同时实现稳定的相位中心并且能抗三个宽带干扰的功能。

It is a novel and significant problem to construct an anti-jamming antenna array with zero phase center antenna on the same floor.Zero-phase antenna requires the grounding plate under the antenna array to be completely weighed,while anti-jamming antenna array requires each element to be centered on the grounding plate and evenly rotated.Therefore,this paper presents a novel method to synthesize a "virtual" zero-phase array directly from four anti-jamming elements,so that the antenna array can simultaneously achieve stable phase center and can resist three broadband interference functions.
