摘　　要：文中着重研究了S波段双偏振相控阵天气雷达幅相一致性的分析方法,将产生一致性差异的误差源分为四个大类八个小类,逐项分析误差源产生的机理,并分析每种误差源可以使用的标校方法和标校精度,最终获得双偏振幅相一致性可实现的预计修正效果。作为S波段双偏振相控阵天气雷达的基础技术研究,对雷达项目的工程研制起到了重要的技术支撑作用。The methodology is focused on of consistency analysis of both magnitude and phase for S-band dual-polarized weather radar. Error sources affecting the magnitude and phase consistency are classified into four main types, and eight types in detail. The physical mechanism, calibration technique, and calibration precision of each type error source are comprehensively analyzed, achieving predictable correction of the magnitude and phase consistency of orthogonal channels. The error analysis and calibration techniques in this paper are essential for the development S-band dual-polarized weather radar, and strongly support the radar engineering.
