摘　　要： 针对采用圆极化天线单元的共形球面阵天线,提出一种基于扫描角变化的相位补偿方法,通过在球面阵天线原有布局的基础上对天线单元进行相位补偿,解决某些角度主极化扫描波束无法形成的问题。仿真结果表明,方法可有效解决圆极化球面阵非同向极化现象造成的方向图恶化问题。 Aiming at the conformal spherical array antenna with circular polarization antenna elements,a phase compensation method based on the change of scanning angle is proposed,which solves the problem that some of the main polarization scanning beams can not form through the phase compensation of the antenna elements on the basis of the original spherical array antennna.Simulation results show that this method can effectively solve the problem of the worse radiation pattern caused by the non-collinear polarization of circular polarization spherical array.
