一种机载大型雷达精细化测角零值标定方法OA

Aiming at the irregular errors caused by the coupling of radome and airframe scattering in beam di-rection of large airborne radar,this paper proposes a refined and highly-efficient calibration method.In this meth-od,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 re-sults verify the effectiveness of the proposed method.
