摘要
阐述了用串馈矩阵开关BIT测试系统对有源相控阵天线的检测和校正 ,分析了校正时在角度θ =sin- 1(λ/λg)出现大副瓣的原因 。
The calibration of active antenna by using RF matrix switch built in test system is discussed in this paper. The BIT system is a series travelling wave network. Appearing of large side lobe at the angle θ=sin -1 (λ/λg) is analyzed. Finally, the compensation methods of the error generating the large side lobe are presented.
