RNTW01 - Rich and Nonlinear Tomography (RNT) in Radar, Astronomy and Geophysics

The high resolution, all-weather, remote sensing of Synthetic Aperture Radar (SAR) imaging is already employed for a wide range of tasks from mapping, surveillance, environmental monitoring and many other uses. Interferometry allows a pair of SAR images from slightly different grazing angles to be used to estimate height within a scene, but this provides a single estimate for each pixel in the image and has limitations in complex environments where layover and multipath may mean that there are reflections from multiple objects in the same pixel. SAR tomography expands the usual 2-D images to generate 3-dimensional images of an area allowing greater understanding of the objects in a scene. This talk provides some background on SAR and the challenges in producing tomographic images.
