摘　　要：针对机载大型雷达的波束指向受天线罩、机体散射耦合影响而产生的非规则误差,本文提出了一种精细化高效率标定方法.该方法中雷达无需发射,综合利用无人机挂载小型标定源和采取多项式拟合的方法实现快速误差标定.仿真结果验证了该方法的有效性.Aiming at the irregular errors caused by the coupling of radome and airframe scattering in beam direction of large airborne radar,this paper proposes a refined and highly-efficient calibration method.In this method,the radar does not need to transmit,and the rapid error calibration is achieved by comprehensively using UAV mounted with small calibration source and adopting sinusoidal space polynomial fitting method.Simulation results verify the effectiveness of the proposed method.
