Baseline Estimation is important for deriving accurate heights in processing of InSAR（Interferometric Synthetic Aperture Radar）. It needs large quantities of ground control points with proper placements to estimate baseline parameters for multiple InSAR data that cover large areas if adopting baseline estimation algorithm for each pair of data. What’s more, there will be great difference between heights derived from different data due to the errors of baseline estimation. A new baseline estimation algorithm with block adjustment considering phase offset was proposed to reduce the needed ground control points and the difference between heights derived from different data. The experiments of baseline estimation with block adjustment were done with multiple pairs of InSAR data obtained by airborne InSAR system researched by Institute of Electronics, Chinese Academy of Sciences. It used less ground control points, and the difference between heights in overlap areas was reduced, as validate
