摘要
提出了一种新的机载条带式SAR沿航向运动误差的补偿方法 .它不用插值 ,所以节省了运算量、避免了插值带来的图像质量下降 ,因而对机载SAR系统的实时成像有好的应用前景 .理论分析、仿真和实测数据成像证明了该方法的正确性和有效性 .
A method for along-track motion compensation of the airborne strip-map SAR(Syn thetic Aperture Radar) is presented.No complex interpolation is involved in this algorithm,hence the high computational efficiency and the improved image quality are achieved.Theor etical analys is,simulation results and the real data images show that it is of great value in real-time imaging.
