摘要

采用高分辨率合成孔径雷达(SAR)定位对提高测绘精度至关重要。设计了两个实验，研究了地面控制点的空间分布和质量对地理偏差的影响。第一组实验对gcp的空间分布采用不同的选择方法，得到地理偏差影响下不同分布方式的gcp;在第二组实验中对gcp的质量采取不同的选择方法，得到地理偏差影响下不同质量选择方式的gcp。两组实验结果表明，道路交叉口或路口点的一致性误差明显小于山川边界的一致性误差，均匀空间分布的一致性误差比不均匀空间分布的一致性误差更明显。

Orientation performance of high resolution SAR imagery

Using high resolution Synthetic Aperture Radar (SAR) Orientation is vital for improve the accuracy of mapping. Two experiments were designed to examine the spatial distribution and quality of the ground control points (GCPs) on the influence of geographical deviation. Take different selection method for the spatial distribution of the GCPs in the first set of experiments and get GCPs with different distributed manner for the impact of geographical deviation; Take different selection method for the quality of the GCPs in the second set of experiments and get GCPs with different quality selection manner for the impact of geographical deviation. From the two groups of experimental results revealed that the errors of road intersections or corner points is evidently smaller than that of mountains and rivers boundary and the consistency error of uniform spatial distribution is more obvious than nonuniform spatial distribution.
