It is found that there is decorrelation increasing with time but that digital terrain model generation remains feasible and such a technique could provide a global digital terrain map.
A new method for measuring deformation on volcanoes and other natural terrains using InSAR persistent scatterers
We present here a new InSAR persistent scatterer (PS) method for analyzing episodic crustal deformation in non‐urban environments, with application to volcanic settings. Our method for identifying PS…
Satellite radar interferometry: Two-dimensional phase unwrapping
Interferometric synthetic aperture radar observations provide a means for obtaining high-resolution digital topographic maps from measurements of amplitude and phase of two complex radar images. The…
Persistent scatterer interferometric synthetic aperture radar for crustal deformation analysis, with application to Volcán Alcedo, Galápagos
 While conventional interferometric synthetic aperture radar (InSAR) is a very effective technique for measuring crustal deformation, almost any interferogram includes large areas where the…
Microwave Radar and Radiometric Remote Sensing
This comprehensive and up-to-date resource provides you with theoretical models, system design and operation, and geoscientific applications of active and passive microwave remote sensing systems.
Atmospheric effects in interferometric synthetic aperture radar surface deformation and topographic maps
Interferogram images derived from repeat-pass spaceborne synthetic aperture radar systems exhibit artifacts due to the time and space variations of atmospheric water vapor. Other tropospheric…
Mapping small elevation changes over large areas: Differential radar interferometry
A technique that uses synthetic aperture radar (SAR) images to measure very small (1 cm or less) surface motions with good resolution (10 m) over large swaths (50 km) is presented along with…
Two-dimensional phase unwrapping with use of statistical models for cost functions in nonlinear optimization.
This work develops a maximum a posteriori probability (MAP) estimation approach for interferometric radar techniques, and derives an algorithm that approximately maximizes the conditional probability of its phase-unwrapped solution given observable quantities such as wrapped phase, image intensity, and interferogram coherence.
Topographic mapping from interferometric synthetic aperture radar observations
Interferometric synthetic aperture radar observations provide a means for obtaining high-resolution topographic terrain maps from data acquired simultaneously at two slightly displaced antennas.…
Measuring two‐dimensional movements using a single InSAR pair
We present a new method to extract along‐track displacements from InSAR data, based on split‐beam InSAR processing, to create forward‐ and backward‐looking interferograms. The phase difference…
