| Abstract: | Aiming at the impact of phase array antenna channel errors on beam-forming,the error source is analyzed,and how the channel errors impacts the beam performance is explained based on beam forming principle.The Simulation results of beam patterns in multiple scenes of amplitude errors and phase errors combination are given and the impact of channel errors on main specifications such as beam width,sidelobe level,gain,etc.is analyzed.At last,the channel errors margin during beam forming is given. |
