中文摘要：
针对干涉合成孔径雷达中存在的基线误差会严重影响高程测量的精度问题，提出了一种新的干涉合成孔径雷达基线及卫星平台高度误差估计方法。利用地面目标点的信息．通过子空间投影的方法估计精确的干涉相位进而得到估计的基线误差。该方法不需要迭代搜索，运算量小．估计精度较高．对解缠的干涉相位具有较高的稳健性．且对噪声具有良好的抑制作用。
英文摘要：
In the Interferometric SAR, the existence of the baseline error and height error of the satellite will affect the precision of the altitude information transformed from the interferometric phase. A new baseline estimation method for InSAR is proposed in this paper. This method is based on subspace projection and in this method the information about some points on the ground is used. This method needs a little amount of computation and has a high estimation precision. It is highly robust to the unwrapping phase and can restrain the noise well. Its validity is illustrated through computer simulations.
