Performance of 3-D Surface Deformation Estimation for Simultaneous Squinted SAR Acquisitions

Application of Sar Interferometric Techniques for Surface Deformation Monitoring

Over the last years surface deformation monitoring with interferometric SAR (INSAR) techniques reached some maturity. Important elements contributing to this increasing importance included the development of advanced processing techniques and the rich existing SAR data archives containing information on surface movements since 1991, the currently operated SAR sensors in orbit (ERS-2, ENVISAT AS...

Prediction of Respiration-Induced Internal 3-D Deformation Fields From Dense External 3-D Surface Motion

High Resolution Sar Imagery for Surface Deformation Assessment

The geodetic information of the terrain can be measured using remote sensing techniques such as photogrammetry, airborne laser scanner (ALS) and interferometric synthetic aperture radar (InSAR). They are considered to be more cost-effective and complementary to conventional ground-based surveying methods. Differential InSAR (DInSAR) can be further used to monitor the dynamic change of the terra...

Atmospheric Artifacts in Interferometric SAR 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 variations, such as pressure and temperature, also induce distortions, but the effects are smaller in magnitude and more evenly distributed throughout the interferogram than the wet troposphere term. Spati...

Bayesian Estimation of Intra-operative Deformation for Image-Guided Surgery Using 3-D Ultrasound

This paper describes the application of Bayesian theory to the problem of compensating for soft tissue deformation to improve the accuracy of imageguided surgery. A triangular surface mesh segmented from a pre-operative image is used as the input to the algorithm, and intra-operatively acquired ultrasound data compounded into a 3-D volume is used to guide the deformation process. Prior probabil...
