本文研究了由定位测量仪器和数字高程模型误差引起的残余未补偿运动误差对机载合成孔径雷达（SAR）图像精度的影响。结果表明，这不仅会引入纯粹几何考虑的相位误差，而且还会导致与SAR处理过程相互作用相关的额外像差。扩展到重复通道机载干涉测量也包括，以显示其对产生的干涉授予的影响。
This work addresses the study of the effect of residual uncompensated motion errors due to positioning measurement instrument and digital elevation model inaccuracies on the accuracy of airborne synthetic aperture radar (SAR) images. It is shown that these not only introduce phase errors following pure geometric considerations, but they also cause additional aberrations related to their interaction with the SAR processing procedure. Extension to the repeat pass airborne interferometry is also included to show their impact on the resulting interferogrants.
