Here, Persistent Scatterer Interferometric (PSI) Synthetic Aperture Radar (SAR) technique has been applied on 13 scenes of ascending track acquired by Advanced Land Observation Satellite Phased Array L-band Synthetic Aperture Radar (ALOS PALSAR) from July 2007 until November 2010 for characteristic analysis of the landslide. The technique is employed to identify and measure land deformation on the earth surface. The PSI technique has good accuracy in overcoming temporal and geometric decorrelation compared to conventional interferometric SAR technique. The result for analyzing landslide deformed area on Kelok Sembilan bridge has been identified. In addition, time series of landslide deformation history were used for calculating the past velocity and acceleration of landslide as well as for estimating for the future.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Acceleration analysis,Characteristic analysis,L-band synthetic aperture radars,Land deformation,Landslide deformation,Observation satellites,Persistent scatterer interferometry (PSI),Persistent scatterers[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Acceleration,land deformation,Persistent Scatterer Interferometry (PSI),Synthetic Aperture Radar (SAR),velocity[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors wish to thank Chiba University for the Scholarship, Japan Aerospace Exploration Agency (JAXA) for ALOS PALSAR data, and SARPROZ for providing processing tool for data.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/TSSA.2017.8272930[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
