Radar Polarimetry Radar Interferometry and Polarimetric SAR Interferometry represent the current culmination in ‘Microwave Remote Sensing’ technology, but we still need to progress very considerably in order to reach the limits of physical realizability. Whereas with radar polarimetry the textural fine-structure, target orientation, symmetries and material constituents can be recovered with con...

It is a high-resolution radar imaging is interdisciplinary and has wide interests among many various areas.In it remote sensing, Synthetic Aperture Radar images are widely usually used to map the land of the terrain.in defense industry, it type of radar imaging of moving objects is an important tool for automatic target recognition. In this review paper, we provide a comprehensive review of rec...

Radar interferometry is a technique which makes use of interfered signal of two radar echoes for topographic elevation and terrain element mapping. ERS Synthetic Aperture Radar (SAR) tandem pair with minimum possible temporal baseline of 1-day and with precise orbit control to obtain suitable interferometric spatial baseline is appropriate for interferometric study in terrain analysis. In this ...

We study circular synthetic aperture radar (CSAR) systems collecting radar backscatter measurements over a complete circular aperture of 360 degrees. This study is motivated by the GOTCHA CSAR data collection experiment conducted by the Air Force Research Laboratory (AFRL). Circular SAR provides wide-angle information about the anisotropic reflectivity of the scattering centers in the scene, an...

Precise corrections with a three-dimensional voxel model of the ionosphere based on global navigation satellite system (GNSS) data from a wide-area network of ground receivers can help resolve differential carrier-phase ambiguities over very long baselines of hundreds of kilometers in present two-frequency systems [global positioning system (GPS) and global orbiting navigation satellite system ...

This paper discusses the RADARSAT-1 Antarctic Mapping Project (RAMP). RAMP is a collaboration between NASA and the Canadian Space Agency (CSA) to map Antarctica using the RADARSAT -1 synthetic aperture radar. The project was conducted in two parts. The first part, which had the data acquisition phase in 1997, resulted in the first high-resolution radar map of Antarctica. The second part, which ...

SAR images experience significant range walk and, without some form of motion compensation, can be quite blurred. The MITREdeveloped Keystone formatting simultaneously and automatically compensates for range walk due to the radial velocity component of each moving target, independent of the number of targets or the value of each target’s radial velocity with respect to the ground. Target radial...

Interferometric synthetic aperture radar (InSAR) is a powerful geodetic tool used to construct digital elevation models of the earth’s topography and to image centimeter-scale displacements associated with crustal deformation and the flow of ice sheets. The past decade has seen significant improvements in our understanding of earthquakes, volcanoes, and glaciers as a direct result of this techn...

The paper focuses on the differential interferometric SAR (Synthetic Aperture Radar) technique for the monitoring of terrain surface deformations. The paper begins with a concise description of the properties of the differential interferometric phase, which represents the main observation for the estimation of the deformations. Then the paper discusses of the main features of a new interferomet...
