摘要
为了对大地进行更精确的测量,重现大地本身地貌,在机载SAR成像时,可利用INS(惯性导航系统)与GPS(全球定位系统)融合后的数据做运动补偿。具体包括融合数据所在的大地坐标系到机载SAR的成像坐标系的坐标变换、机载SAR运动补偿的实现。最后通过实际数据的成像给出运动补偿的效果。
To measure the earth more accurately, a new motion compensation method for airborne SAR based on the fusion of INS and GPS was presented. Before the compensation, coordinates transform should be made. Finally, motion compensation result indicated the effectiveness of the proposed method.
