A radar interferometric technique for topographic mapping of surfaces promises a high resolution, globally consistent approach to generation of digital elevation models. A radar interferometric technique for topographic mapping of surfaces, implemented utilizing a single synthetic aperture radar (SAR) system in a nearly repeating orbit, is discussed. The authors characterize the various sources contributing to the echo correlation statistics, and isolate the term which most closely describes surficial change. A radar interferometric technique for topographic mapping of surfaces promises a high resolution, globally consistent approach to generation of digital elevation models. One implementation approach, that of utilizing a single synthetic aperture radar system in a nearly repeating orbit, is attractive not only for cost and complexity reasons but also There are no files associated with this item. title: Decorrelation in interferometric radar echoes: Author(eng) Zebker, Howard A.; Villasensor, John in place the interferometric analysis (and/or decorrelation) over vegetation (or prime targets covered by vegetation i.e., potential land sliding hot spots) is a challenging task. The main reason behind this inconsistency is predominantly because of volume scattering and temporal decorrelation [15].

This paper puts forward these two concepts to polarimetric interferometric SAR (Pol-InSAR) forest height estimation application. The application makes use of volume decorrelation, which is also a A radar interferometer images the ground using two antennas located at points S 1 and S 2, separated by a baseline, B, with components normal to, and parallel to, the radar look direction (B n and B p; Fig. 2).

• The two radar (SAR) antennas act as coherent point sources! • SAR image is equivalent to a phase and amplitude detector.!! • Two SAR images can then be Among these are temporal atmospheric changes from pass to pass, uncertainties in the orbit of the satellite, necessitating estimation of the interferometric geometry from the data themselves, and decorrelation of the radar echoes from pass to pass because of rearrangement of scatterers on the surface [Goldstein, Interferometric baseline performance 29 minedbythesizeofthesatellite-to-satellitebaselinedistance and the accuracy of its reconstruction, as well as the quality of the interferometric phase correlation. During the Shut-tle radar topographic mission (SRTM), e.g., the interfero-metric performance was limited by the fixed 60m boom (Werner 2001).
