Compared with low-Earth orbit synthetic aperture radar (SAR), a geosynchronous (GEO) SAR can have a shorter revisit period and vaster coverage. However, relative motion between this SAR and targets is more complicated, which makes range cell migration (RCM) spatially variant along both range and azimuth. As a result, efficient and precise imaging becomes difficult. This paper analyzes and model...

The Commission for Racial Equality (Special Educational Needs Assessment in Strathclyde: Report of a Formal Investigation, CRE, London, 1996) highlighted the significant under-representation of bilingual children among pupils assessed as having specific learning difficulties/dyslexia. In this present study an audit was undertaken in order to explore issues arising from the Commission's report, ...

In 2001 the Intergovernmental Panel on Climate Change issued its Third Assessment Report on the prospects for and likely impact of increases in global average temperature over the next century. The summary report of Working Group 1, on science, widened the range of likely temperature increase, compared with the IPCC's Second Assessment Report five years earlier, to 1.4-5.8 degrees centigrade, w...

Abstract. The salt mining industrial exploitation located in Vauvert (France) has been injecting water at high pressure into wells to dissolve layers depth. extracted brine used the chemical industry for more than 30 years, inducing a subsidence of surface. Yearly leveling surveys have monitored deformation since 1996. This dataset is supplemented by synthetic aperture radar (SAR) images, and 2...

Synthetic aperture radar (SAR) is an indispensable tool for low visibility ground surface measurement owing to its robustness against optically harsh environments such as adverse weather or darkness. As a leading-edge approach for SAR image processing, the coherent change detection (CCD) technique has been recently established; it detects a temporal change in the same region according to the ph...
