Sea surface height measuring using InSAR altimeter
Geodesy and Geodynamics, 2017 Satellite altimetry has been widely used in measuring ocean topography from space. The conventional altimeter system is the nadir radar altimeter system which has the limitations of one-dimensional measurement and is unable to get both high temporal and ...

Engineering Reports, Volume 8, Issue 4, April 2026.The test results displayed reveal that the proposed method efficiently accomplishes the remote sensing image processing of the area, yielding a differential interferogram of the image. This interferogram accurately represents the area and provides a solid foundation for calculating the environmental hazard zone within the construction area.

Coseismic surface deformation from air photos: The Kickapoo step over in the 1992 Landers rupture [PDF]
, 2006 Coseismic deformation of the ground can be measured from aerial views taken before and after an earthquake. We chose the area of the Kickapoo-Landers step over along the 1992 Landers earthquake zone, using air photos (scale 1:40,000) scanned at 0.4 m ...

Multibaseline Polarimetric SAR Interferometry Coherence Optimization [PDF]
IEEE Geoscience and Remote Sensing Letters, 2008 This letter analyzes different approaches for polarimetric optimization of multibaseline (MB) interferometric coherences. Two general methods are developed to simultaneously optimize coherences for more than two data sets. The first method provides every data set with a distinct dominant scattering mechanism (SM).

Correction of Non‐Geophysical Errors in SAR Doppler Shift for Ocean Surface Current Retrieval
Earth and Space Science, Volume 13, Issue 4, April 2026.Abstract Synthetic aperture radar (SAR) data contains Doppler information on ocean surface movement, and the Doppler centroid anomaly (DCA) can be used to quantitatively retrieve ocean surface currents in the line‐of‐sight of radar. However, non‐geophysical errors (NGE) in Doppler information significantly affect retrieval accuracy. Generally, existing
