对机载合成孔径雷达（ＳＡＲ）的平台姿态进行了分析，给出了适于利用回波自身补偿的横滚、偏航及俯仰角的变化范围，并将惯性导航系统（ＩＮＳ）和全球定位系统（ＧＰＳ）结合起来用于校正较大范围的平台姿态变化；而对精细校正，则利用回波原始数据实现。
The attitude of airborne Synthetic Aperture Radar (SAR) platform is analyzed. The range of roll, yaw and pitch angle suitable for echo self-compensation is given. The inertial navigation system (INS) and global positioning System (GPS) is used to correct a wide range of platform attitude changes, while for fine corrections, echo raw data is used.
