本文研究了利用雷达测量距离-多普勒方程对城区分米分辨率机载多方位合成孔径雷达（MASAR）数据进行配准的问题。的几何模型是适应线性飞行轨迹和零多普勒处理的SAR数据，而观察到的轨迹参数进行调整，使用严格的高斯-赫尔默特模型和已知的地面控制点。估计的校正的意义进行检查，并确定最合适的一组自由参数。最后，该方法被应用到真实的测试数据的机载运动在城市的慕尼黑，德国，和所提出的雷达测量配准方法的可行性。
In this paper, the registration of decimeter-resolution airborne multi-aspect SAR (MASAR) data of inner city areas by application of the radargrammetric range-Doppler equations is investigated. The geometrical model is adapted to linear flight trajectories and zero-Doppler processed SAR data, whereas the observed trajectory parameters are adjusted using a strict Gauss–Helmert model and known ground control points. The significance of the estimated corrections is examined and the most suitable set of free parameters is determined. Finally, the methodology is applied to real test data of an airborne campaign over the city of Munich, Germany, and the feasability of the proposed radargrammetric registration method is shown.
