摘　　要：研究了某偏馈栅格天线的栅面误差仿真技术。在分析栅格天线装配过程基础上,建立了其反射面装配的仿真模型,并对栅支板中心圆孔位置误差、栅条穿入误差和栅面误差进行了建模与仿真计算。对影响栅面精度的关键因素进行了讨论和优化。通过对比实验,验证了仿真结果的合理性。The error simulation technology of a kind of grid antenna is studied in this paper. Based on research of the antenna＇s assemble procedure, the simulation model of the reflector is set up and error modeling and simulation of position of stick holes, grid bar acrossing the hole and RMS of reflector face are achieved. Key factors that affect the precision of reflector are debated and optimized. The correctness of simulation result is verified by experiment.
