SUMMARY:Introduction to SAR tomography - Malcolm Stevens (Thales)

DESCRIPTION:The high resolution\, all-weather\, remote sensing of Syntheti
 c Aperture Radar (SAR) imaging is already employed for a wide range of tas
 ks from mapping\, surveillance\, environmental monitoring and many other u
 ses. Interferometry allows a pair of SAR images from slightly different gr
 azing angles to be used to estimate height within a scene\, but this provi
 des a single estimate for each pixel in the image and has limitations in c
 omplex environments where layover and multipath may mean that there are re
 flections 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 b
 ackground on SAR and the challenges in producing tomographic images.
