中文摘要：

在有效融合GPS与InSAR两种对地观测技术提高地表三维形变监测精度时,针对InSAR监测结果中可能存在的系统偏差,建立了附加系统参数的综合形变分析模型。该模型以高精度的GPS观测数据作为强约束,将InSAR数据中的系统误差综合影响用函数拟合的方法进行补偿。模拟数据和实测数据计算表明,附加系统参数的综合形变分析方法在E、N、U3个方向的精度都有所提高,其中以U方向最为显著。

英文摘要：

Considering the systematic differences between InSAR monitoring deformation and GPS ob servation, an integrated deformation analysis model with additional systematic parameters is established for the three-dimensional deformation field, in order to integrate GPS and InSAR data effectively. In this model, systematic parameters are added under the constraint of high accurate deformation derived from GPS to compensate system error in InSAR derived deformation. Both simulated and measured data prove the significance of our method in improving the accuracy of three deformation components, especially in U direction.
