为有效减少大面积、多套干涉数据基线估计所需的地面控制点数量、降低接边处反演高程的差异,提出考虑干涉相位偏置的InSAR区域网平差基线估计方法。采用中国科学院电子学研究所机载InSAR系统获取的多套干涉数据进行了区域网平差基线估计试验,利用少量地面控制点完成了各套干涉数据的基线估计,减小接边处反演高程的差异,验证该基线估计方法的有效性。 更多还原

【Abstract】 A new baseline estimation algorithm with block adjustment considering phase offset for multiple InSAR data that cover large areas is proposed to reduce the number of needed ground control points and the difference between heights derived from different data.The experiments of baseline estimation with block adjustment are done with multiple pairs of InSAR data obtained by airborne InSAR system researched by Institute of Electronics,Chinese Academy of Sciences.It uses less ground control points.Th... 更多还原
