文摘

Gain large area InSAR subsidence over southern lower Liaohe plain at the first time Recover the maximum deformation by determining unwrap grid size Calibration the neighboring offset by weighted mean value of overlapped region Standard deviation is 0.91 cm/year achieving by two independent vertical deformation. Analyzed the causes of the deformations in different regions of Liaohe plain
