“…Among these innovations, the Persistent Scatterer SAR Interferometry (PSI) technique, first proposed by [17] was further developed to monitor the temporal evolution of deformation on each Permanent Scatterer (PS) to produce a deformation rate map at the millimeter level by processing time series SAR images [8,[18][19][20][21][22][23][24]. These techniques have been proven to be an efficient method for investigating the spatial and temporal pattern of surface deformation [20,[25][26][27][28].…”

Many coastal cities have undertaken reclamation projects to satisfy the land demands of rapid urbanization. However, the foundations of reclaimed land are susceptible to settlement and can have undesirable environmental impacts that could adversely affect these dense, populated areas. In the case of international airports built on reclaimed areas especially, regional-scale deformation must be monitored to ensure operational security for public safety. Persistent Scatterer SAR Interferometry (PSI) technology has proven to be an effective tool to detect ground deformation in urban areas. However, it is still a challenge to apply PSI to effectively monitor settlement at airports built on newly developed coastal reclamation areas because of the scarcity of identifiable targets. Moreover, additional issues arise as the complicated deformation patterns associated with the underlying geological conditions make it difficult to interpret InSAR-derived results. In this study, a time-series analysis of a high-resolution TerraSAR-X satellite image stack acquired from September 2011 to October 2012 was performed by employing a modified PSI technique to retrieve the mean deformation velocity and time series of surface deformation at Pudong International Airport. Qualitative evaluation of spatial distribution and temporal evolution of deformation was conducted by joint analyses of deformation measurements and local geological data. Detailed analysis of various driving forces for deformation patterns confirmed that the results of deformation monitoring obtained by PSI are reliable and consistent with that of local geological surveys. Since the factors responsible for the subsidence within the airport are still at play, ongoing and routine deformation monitoring is warranted.

“…These methods are time-consuming, labor-intensive, costly, and limited in spatial coverage and precision. With the rapid progress in Earth observation techniques in recent years, different interferometric synthetic aperture radar (D-InSAR) and time-series InSAR methods such as PS-InSAR [5][6][7][8], SBAS-InSAR [9][10][11][12][13][14][15][16], TCP-InSAR [17][18][19][20], and ITPA-InSAR [21,22] have been proven to be effective methods with an accuracy of millimeters to centimeters for mapping ground deformation induced by various natural and anthropogenic causes. However, those methods are based on phase unwrapping and have significant limitations based on deformation gradient.…”

An Improved Adaptive Template Size Pixel-Tracking Method for Monitoring Large-Gradient Mining Subsidence

et al. 2017

The monitoring of large-gradient deformation caused by coal mining is of great significance to the prevention and management of disasters in mining areas. The interferometric synthetic aperture radar (InSAR) method captures the small-gradient ground deformation on the edge of the subsidence basin accurately but is unreliable for capturing large-gradient deformation. The intensitybased pixel-tracking method (e.g., the normalized cross-correlation (NCC) method) can overcome the limitations of InSAR's maximum detectable displacement gradient and incoherence. However, the pixel-tracking method is sensitive to template size. It is difficult to estimate ground subsidence accurately by the conventional pixel-tracking method with fixed template size. In this paper, the signal-to-noise ratio (SNR) is redefined and an improved locally adaptive template size method is proposed by identifying optimal template adaptively based on maximization of the redefined SNR. The constraint radius is used to constrain the search area in this improved method. The frequency of misrepresentation is reduced by finding the peak of the correlation coefficient surface within the search area. Both simulation data and real ground subsidence data are used to test this algorithm. The results show that this method can improve monitoring accuracy compared with the traditional pixel-tracking method for fixed template size.

“…Since the selected coherent points keep stable in the time series respective to their phase and amplitude, they are less likely to be influenced by temporal and spatial baseline, which helps better overcome traditional D-InSAR technique's vulnerability to temporal and spatial decorrelation. Presently some scholars have already applied this technique to subsidence monitoring in coal mining [Abdikan et al, 2014;Yan et al, 2014;Bateson et al, 2015]. However, when drastic deformation happens in coal mining areas such as ground collapse, its deformation gradient exceeds the maximum detectable gradient range of InSAR, a series of dense interferometric fringes will appear in the interferogram.…”

Coal mining usually causes drastic large gradient deformation in the earth's surface in a short period, which leads to the formation of collapse basin or collapse pit. The drastic deformation renders the generation of dense fringes in interferogram, leading to difficulties in the phase unwrapping step. In this paper we propose using intensity tracking technique to monitor large gradient deformation in the subsidence center. To obtain the small deformation information around the basin and collapse pit, we use Small Baseline Subset (SBAS) interferometry technique to monitor the small deformation , after which we integrate the results under the two methods to obtain complete monitoring results. We take Daliu Tower mining of Shanxi Province in China as an example, using TerraSAR-X satellite data of 13 scenes spanning from 21/11/2012 to 02/04/2013 to conduct deformation monitoring experiment. The experiment result shows that the proposed method has the capability to detect and measure the large gradient deformation, meanwhile, small deformation information is preserved. Moreover, by comparing the experiment monitoring results to continuous GPS measurements, we estimate that the accuracy of deformation monitor is about 8 cm in the range direction.
