Geodetic 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...
متن کاملGround Deformation Mapping Using Insar
SAR interferometric data can be used for extracting three dimensional information of the earth’s surface by using the phase part of the radar signal. In this study, available SAR interferometric data acquired before and after the Marmara earthquake of 1999 and provided by ESA were used for mapping the ground deformation in the satellite line of sight (LOS) in the Izmit province. The interferome...
متن کاملOn 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 کاملGround-based SAR data analysis tools for deformation monitoring
In the last years, the Ground-Based SAR (GBSAR) technique has proved to be a reliable tool for deformation measurement and monitoring. Compared with other point-wise geodetic techniques it can provide “continuous” displacement measurements over areas of few squared kilometers, with a high spatial resolution and precision up to millimeter level. The process of estimating deformation from the GBS...
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...
