摘　　要：为了解决载体的偏航、俯仰和滚转误差难以完全补偿的问题,提出一种利用SINS+GPS组合导航信息的机载SAR成像实时角度补偿方案。成像处理启动时刻记录载体的姿态信息作为基准,成像过程根据导航信息实时补偿天线指向,计算准确的下视角和斜视角。挂飞实验证明,这种角度补偿方案能够为实时成像提供准确的输入参数,提高成像质量。To eliminating the angle error of airborne SAR, a scheme for real-time angle compensation in airborne SAR imaging is proposed. The original guise information of the carrier is memorized as a reference. According to the reference in formation, the real-time angle of the APC can be emendated. Experiments show that the new method can provide accurate parameters for airborne SAR imaging and is useful to improve the image quality.
