Synthetic aperture radar with multiple channels separated in along-track direction allows for GMTI such as detection of road traffic [1]. With TerraSAR-X two receive channels separated in along-track direction can either be realized through switching between the fore and aft antenna halves from pulse to pulse, or with the dual receive antenna (DRA) mode [2]. While the switching in the single ch...

Geometric correction of SAR satellite imagery is the process to adjust the model parameters that define the relationship between ground and image coordinates. To achieve sub-pixel geolocation accuracy, the adoption of the appropriate geometric correction model and parameters is important. Until now, various geometric correction models have been developed and applied. However, it is still diffic...

Recently high-resolution space-borne synthetic aperture radar (SAR) systems with various polarizations have been launched and operated successfully. Data acquired by these systems have shown good results for various geodetic interferometric SAR (InSAR) applications [1-5]. In this study we evaluate the coherences characteristics of high-resolution data acquired by TerraSAR-X (X-band), ALOS (L-ba...

Most of the image processing techniques have been first proposed and developed on small size images and progressively applied to larger and larger data sets resulting from new sensors and application requirements. In geosciences, digital cameras and remote sensing images can be used to monitor glaciers and to measure their surface velocity by different techniques. However, the image size and th...

Most icebergs present in northern latitudes originate from western Greenland glaciers, from where they drift into Baffin Bay, circulating north along Greenland coast and south along Canadian coast. Some of them drift more southwards up to Newfoundland, where they frequently cross shipping routes. Furthermore, the Arctic summer sea ice coverage significantly decreased over the last three decades...

13 We apply an image correlation technique to multi-orbit and multi-temporal High-Resolution (HR) SAR 14 data. Image correlation technique has the advantage of providing displacement maps in two 15 directions; e.g. the Line of Sight direction (LoS) and the Azimuth direction. This information, derived 16 from the two modes of data acquisition (ascending and descending), can be combined routinely...

An L-band SAR mission is a proposed to meet the requirements of the European Space Agency (ESA) Earth Observation Preparatory Programme (EOPP). The L band SAR instrument (L-SAR) has been studied as part of a pre-phase A contract for ESA (LandSAR). The L-SAR is also one component of the L+X-band TerraSAR system. TerraSAR has been proposed for the overall Earth Watch programme and is also the maj...

Stereo positioning is a important content for Spaceborne SAR imagery mapping, which is still lack of investigation depend on exterior orientation elements. In this paper, we firstly introduced the Range-Coplanarity (R-Cp) geometric imaging equation and its character for radar imagery, compared the difference and relationship between R-Cp and R-D model, and build stereo positioning rigorous mode...

The last three decades have seen significant mining development in the northern regions of Canada, where the freeze and thaw cycle of permafrost and corresponding surface subsidence and heave represent a significant challenge at all mining stages, from the design of infrastructures to the monitoring of restored areas. Over the past ten years, SAR interferometry has been widely used to monitor g...

The present study investigates the relations between statistical measures of TerraSAR-X backscatter coefficients and field inventory measures for tropical agroforestry systems in Central Sulawesi, Indonesia. The background of the study is to evaluate the potential of spaceborne SAR missions for the spatially explicit estimation of horizontal and vertical structure elements of land use systems i...
