During tandem period of ERS-1/2 (April June 1996), field experiments were conducted in Bhavnagar test site with Corner Reflectors (CRs) to study the sensitivity of differential SAR interferometry to estimate the movements of CRs. Initially, three images acquired on April 4, 5 and May 9, 1996 were processed to generate interferograms. Using single interferogram formed with April 4 and May 9, dur...

The first German space mission TerraSAR-X was launched on June 15th, 2007. Within the TerraSAR-X science program of the German Aerospace Center (DLR), the Institute of Digital Image Processing of Joanneum Research (JRDIB) has gained a principal investigator status with respect to the assessment of the mapping potential of TerraSAR-X data using radargrammetric as well as interferometric techniqu...

As part of a Tanzanian-Norwegian cooperation project on Monitoring Reporting and Verification (MRV) for REDD+, 2007-2011 Cand L-band synthetic aperture radar (SAR) backscatter data from Envisat ASAR and ALOS Palsar, respectively, have been processed, analysed and used for forest and forest change mapping over a study side in Liwale District in Lindi Region, Tanzania. Land cover observations fro...

This paper highlights the potential of combining Synthetic Aperture Radar (SAR) and optical data for operational rapid urban mapping. An algorithm consisting of a completely unsupervised procedure for processing pairs of co-registered SAR/optical images is proposed. In a first stage, a texture analysis is conducted independently on the two images using eight different chain-based Gaussian model...

The institutional framework for Macroprudential Policies (MaPP) in the Hong Kong Special Administrative Region (the SAR) is well established. According to Basic Law, Government of SAR shall on its own formulate monetary and financial policies. Financial Secretary (FS) Services Treasury (SFST) are responsible policies maintaining stability integrity system SAR. has a sector-based regulatory stru...

The performance of the ERS-2 Synthetic Aperture Radar (SAR) is routinely assessed at the ESA Product and Archiving Facilities (PAFs) via a variety of quality assessment and calibration measures. This paper gives the latest ERS-2 SAR quality assessment and calibration results, including updates to ERS-2 SAR internal calibration and stability, noise equivalent radar crosssection measurements, upd...

Two image-to-image patch offset techniques for estimating feature motion between satellite synthetic aperture radar (SAR) images are discussed. Intensity tracking, based on patch intensity cross-correlation optimization, and coherence tracking, based on patch coherence optimization, are used to estimate the movement of glacier surfaces between two SAR images in both slant-range and azimuth dire...
