On InSAR AMBIGUITY RESOLUTION FOR DEFORMATION MONITORING
Integer carrier phase ambiguity resolution is the key to fast and highprecision satellite positioning and navigation. It applies to a great variety of current and future models of GPS, modernized GPS and Galileo. It also applies to stacked radar interferometry for deformation monitoring, see e.g. [Hanssen, et al, 2001]. In this contribution we apply the integer least-squares’ principle to the r...
متن کاملMonitoring Building Deformation with InSAR: Experiments and Validation
Synthetic Aperture Radar Interferometry (InSAR) techniques are increasingly applied for monitoring land subsidence. The advantages of InSAR include high accuracy and the ability to cover large areas; nevertheless, research validating the use of InSAR on building deformation is limited. In this paper, we test the monitoring capability of the InSAR in experiments using two landmark buildings; the...
متن کاملMonitoring Landslides and Volcanic Deformation from Insar Techniques
Our research has shown that interferometric SAR techniques can be used to monitor deformation at landslides and volcanoes under specific conditions. Special filtered interferograms are being used to reduce speckle and minimize errors created by vegetation. InSAR images were used to monitor current post slide motion along existing fault lines at the Frank Slide a 30 x 10 m rock avalanche, in the...
متن کاملOptimal combination of InSAR and GPS for measuring interseismic crustal deformation
High spatial resolution measurements of interseismic deformation along major faults are critical for understanding the earthquake cycle and for assessing earthquake hazard. We propose a new remove/filter/restore technique to optimally combine GPS and InSAR data to measure interseismic crustal deformation, considering the spacing of GPS stations in California and the characteristics of interseis...
متن کاملGeodetic network design for InSAR: Application to ground deformation monitoring
We propose a novel geodetic network design method for InSAR that determines the minimum number and optimal locations of in situ devices for monitoring a deforming area within desired quality constraints (precision, reliability, economy). From field experiments, the use of low-cost active radar transponders has been validated, and their measurement precision estimated. The proposed design algori...
