Abstract

We saw in Chapter 2 that, because it is a coherent imaging system, a synthetic aperture radar transduces the complex reflectivity of the illuminated scene. This reflectivity function, however, is modulated by phase terms that capture the imaging geometry. As a result, an interesting possibility arises when two SAR images are made of the same scene using very close geometries. It becomes possible in this case to interfere the two images in such a way as to cancel the scene reflectivity which is common to both and to recover the geometric information that contains the scene topography transduced by the image-domain phase data. We will use the acronym IFSAR to refer to this type of processing.
