摘要

波束零点对阵列幅相不一致非常敏感

这一点往往降低了利用零点技术抗干扰的性能.为了改善波束零点在实际系统中对干扰的抑制效果

本文通过对理想约束模型进行预畸变处理

大大的降低了天线单元幅相不一致性对波束零点的影响.对该方法的进一步推广

天线单元存在方向性误差和天线单元有缺失情况下的零点合成问题也得到了解决.本文中的仿真结果和实际数据处理结果都进一步证明了该方法的有效性.

Abstract

The sensibility of beams' nulls to the amplitude and phase errors of antenna cells leads to an average losing in suppressing interferences by nulling techniques.In order to improve the suppressing effect of nulling in a practical system

this paper proposes a pre-remedy processing on an ideal constraint model

which obviously takes the influence from antenna errors on pattern nulls.By extending this method

the problem can be solved when the elements of array have directional errors or some element is failed.The simulation results and practical data processing results have shown the effectivity of this method.
