相控阵天线的通道误差对数字波束形成的影响
The influence of channel uncertainty of phased array antenna in digital beam forming
摘要
Abstract
In order to research the influence of channel uncertainty of phased array antenna in digital beam forming,the channel error is modeled,and a conclusion is obtained that the amplitude error between channels has little influence on the beam pointing but can lower the main lobe gain of beam pattern and increase the side lobe level. The phase error can not only re-duce the main lobe gain and raise the side lobe level,but also cause beam pointing deviation. Finally,the result is proved by Matlab simulation.关键词
