【摘要】 作为InSAR系列讲座的第五篇,本文介绍InSAR高程与形变测量中的误差来源,对主要误差源(干涉相位、基线参数和地形数据)推导出误差传播模型。此外,还将讨论地形数据误差对干涉形变测量的影响。更多还原

【Abstract】 As the fifth part of the tutorial, the paper introduces and discusses the sources of errors in elevation/deformation measurements derived with InSAR, and conducts modeling for the main error sources (i.e., interferometric phases, baseline parameters and topographic datasets) based on the error propagation law. Finally discussed is the influence of errors in topographic datasets used in differential interferometry for deformation mapping.更多还原
