Abstract：On the basis of analyzing the relations between positioning and deformation measuring accuracies and baseline error, the importance of baseline estimation was pointed. By comparing and combining three classical baseline estimation methods, a new baseline estimation method and its flow were proposed, and the estimation accuracy affected by squint angle also was researched quantitatively. Finally, by comparing and analyzing the interferograms and sample altitudes generated with different baseline combination methods, the correcness and feasibility of the proposed baseline estimation method are validated.
