INTERFEROMETRIC SYNTHETIC-APERTURE RADAR

Interferometric synthetic aperture radar provides a means of deriving high-resolution three-dimensional radar images of a target scene. this has applications both from satellites for remote sensing purposes, an d from aircraft for military surveillance. The technique is also appli cable to synthetic aperture sonar systems, for applications such as oi l wellhead inspection and minehunting. This paper reviews the principl es of these techniques, illustrating them with examples of results, an d looks at the prospects for the future.
