• Radar has a coherent source much like a laser! • 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 Decorrelation in interferometric radar echoes A radar interferometric technique for topographic mapping of surfaces promises a high resolution, globally consistent approach to generation of digital elevation models.

For each pair we have collected an amplitude image (fig. 1, a), a coherence image (Zebker &Villasenor, 1992)(fig. 1, b), and an image of phase differences(fig. 1, c). Home Browse by Title Periodicals International Journal of Remote Sensing Vol. 28, No. 6 Observations of forest stand top height and mean height from interferometric SAR and LiDAR over a conifer plantation at Thetford Forest, UK Forest-height inversion using airborne double-antenna synthetic aperture radar (SAR) systems has been widely researched, leading to increasing accuracy.

• Two SAR images can then be Decorrelation in interferometric radar echoes 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 SAR system in a nearly repeating orbit, is attractive not only for cost the presence of speckle decorrelation.

Finally, should the arrangement of scatterers physically change between observations, this will result in temporal decorrelation. Temporal decorrelation may be significant in repeat-pass InSAR. Decorrelation in interferometric radar echoes. Geosci. Remote Sens. IEEE Trans.

Decorrelation in interferometric radar echoes

For example, ERS-1 and ERS-2 SAR has a nominal incidence angle range across the swath of 19.4 –26.5 . The C.N.E.S has provided us three interferometric pairs. The images have been acquired between September 1992 and October 1993, during the phase C of ERS1 descending orbits. For each pair we have collected an amplitude image (fig.
