angular calibration of radar antenna system is composed of the calibration of angular error sensitivities ( also called directional sensitivity ), adjustment of cross-coupling of azimuth and elevation signals, and the calibrations of system errors such as antenna axial system error, dynamic delay and so on 雷達系統天線的角度標校包括對系統角誤差靈敏度(又稱定向靈敏度)的標定、方位俯仰信號交叉耦合的調整以及對天線軸系誤差、動態滯后等系統誤差的標定。
