单元交叉极化对自适应阵列性能的影响
The effects of element cross-polarization on adaptive array performance
-
摘要: 该文分析了在存在双极化干扰机条件下的自适应阵列的性能。由于接收天线单元交叉极化方向图不一致性的存在,通过改变两正交极化干扰分量之间的相位,可以导致阵列单元之间的幅相不一致发生变化。这种变化是无法用简单的校正固定幅相误差的方法来加以校正的,从而导致自适应阵列的性能下降。

Abstract: In this paper, the adaptive antenna array performance is given when the dual polarized jamming signals are considered. If the phases of two polarized elements are changed dnring the adaptive weight calculation, the amplitute and phase errors between the antenna elements will be also changed due to the inconsistaricy of the element cross-polarization. This kind of error can not be corrected and the signal to noise plus interference ratio will be rednced. -
