We present a modification to the adaptive Goldstein radar interferogram filter which improves quality of interferometry products. The proposed approach makes parameter alpha dependent on coherence, such that incoherent areas are filtered more than coherent areas. This minimizes loss signal while still reducing level noise.
Abstract The paper presents the results of terrain subsidence monitoring in Poland’s Upper Silesian Coal Basin (USCB) mining area using Differential Interferometry Synthetic Aperture Radar (DInSAR) and Persistent Scatterer (PSI). study accounts for almost three million inhabitants where which started 19th century, has produced severe damage to buildings urban infrastructures past years. analysis aimed combine eight different datasets, processed two techniques, coming from various sensors...
The Goldstein filter is one of the most commonly used synthetic aperture radar (SAR) interferogram filters. This letter proposes a new method to find parameters Goldestein based on noise level derived by empirical mode decomposition (EMD) method. filtering parameter determined this has definite physical meaning. We bidimensional (BEMD) extract features an interferometric phase image into multiple scales spatial frequencies, called intrinsic functions (IMF). constructed pseudo-SNR...
The Goldstein filter is one of the most commonly used filters for synthetic aperture radar (SAR) interferograms. level noise after filtering controlled by a parameter, "alpha," value which determined pixels within moving window. However, when there exist different features single window, especially along border, alpha as estimated from window can be inaccurate and this may result in blurred borders filtered This letter proposes modified based on adaptive-neighborhood technique. idea method...
Geological disasters are responsible for the loss of human lives and significant economic financial damage every year. Considering that these may occur anywhere—both in remote and/or highly populated areas—and anytime, continuously monitoring areas known to be more prone geohazards can help determine preventive or alert actions safeguard life, property businesses. Remote sensing technology—especially satellite-based—can due its high spatial temporal coverage. Indeed, data acquired from most...
Over the recent years, post-mining terrain deformations have been increasingly frequent around Trzebinia. Sinkholes appearing closer and to buildings become a significant geohazard. The research demonstrated that problem of deformation in area is much more extensive than previously estimated. Identification involved analysis historic aerial photographs, airborne laser scanning data, orthophotomaps satellite radar data. Moreover, selected areas using an unmanned vehicle terrestrial scanner...
Synthetic aperture radar (SAR) interferometric baseline parameters form important input for SAR interferometry. In this paper, a nonlinear error model is established the and parameterized as polynomial based on natural nonlinearity of orbit satellite. Unlike conventional models, proposed takes into account part error. A theoretical derivation performed imaging geometry SAR, results analysis show that can be obtained from relationship between orbit, nominal baseline, error, residual...
As a sensitive indicator of climate change, mountain glacier dynamics are great concern, but the ice motion pattern an entire surface cannot be accurately and efficiently generated by use only phase-based or intensity-based methods with synthetic aperture radar (SAR) imagery. To derive movement whole high accuracy, integrated approach combining differential interferometric SAR (D-InSAR), multi-aperture interferometry (MAI), pixel-tracking (PT) method is proposed, which could fully exploit...
The offset tracking technique based on synthetic aperture radar (SAR) image intensity information can estimate glacier displacement even when velocities are high and the time interval between images is long, allowing for broad use of this in velocity monitoring. Terrestrial laser scanners, a non-contact measuring system, measure if there no control points arranged glacier. In study, six COSMO-SkyMed acquired 31 July 22 December 2016 were used to obtain glacial movements five glaciers...
COSMO-SkyMed is a constellation of four X-band high-resolution radar satellites with minimum revisit period 12 hours. These can obtain ascending and descending synthetic aperture (SAR) images very similar periods for use in the three-dimensional (3D) inversion glacier velocities. In this paper, based on data acquired at nearly same time, surface velocity Yiga Glacier, located Jiali County, Tibet, China, estimated directions using an offset tracking technique during 16 January to 3 February...
Conventional four-pass differential synthetic aperture radar interferometry (DInSAR) assumes that there are no significant changes in the ground during period between acquisition times of SAR images for topographic DInSAR pairs. This assumption can rarely be satisfied glacial areas due to their continuous movement. letter proposes a modified method without an external digital elevation model (DEM), taking into account glacier movement used form An explicit expression theoretical formulas...
In this work, DInSAR technique has been applied to the monitoring of mining induced land subsidence in many areas. paper, is used process space borne SAR data including C band ENVISAT ASAR and L JERS, PALSAR derive temporal information Fengfeng coal mine area, Hebei province China. Since JERS do not have precise orbit, an orbit adjustment must be accomplish before interferogram was formed. We designed a images coregistration method based on imaging geometry interferometric SAR, external DEM....
