Decorrelation in Interferometric Radar Echoes by Howard Zebker And, John Villasenor, Howard A. Zebker, Howard A. Zebker , 1992 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.
2020-10-01 · The interferometric synthetic aperture radar temporal decorrelation model is a powerful tool for describing surface changes over time. Recently, this model has been used in several dune stability studies. from September 2003 to September 2005. The loss of coherence (decorrelation) is the main problem in these applications and some precautions were designed to control it. A solid platform, where the radar instrumentation was carefully reinstalled at each campaign, was built specifically in order to avoid geometric decorrelation between different Prof.

The cross-track baseline in InSAR system is very sensitive to terrain fluctuation which is widely used to retrieve the DEM. The cross-track baseline influences the coherence of the radar echoes seriously. In this paper, we analyzed the decorrelation caused by cross-track baseline and the channel mismatch respectively. And a decorrelation reduction method by means of compensating the Delays arising in the ionosphere may have small‐scale variability and decorrelation times that are fundamentally different from the neutral atmosphere. However, in future missions, the effect of the ionosphere may be mitigated by deploying a dual frequency or split band radar system.

The main reason behind this inconsistency is predominantly because of volume scattering and temporal decorrelation [15]. In 2014 TerraSAR-X activated a new acquisition mode, Temporal|) are the main factors affecting the interferometric phase [21]. All of these decorrelation sources add noise to the received radar echoes which increase the standard deviation of not only the phase and phase differences inferred, but also that of the final derived products [22].

The authors characterize the various sources contributing to the echo correlation statistics, and isolate the term which most closely describes surficial change. Abstract—Temporal and geometrical decorrelation often pre-vents SAR interferometry from being an operational tool for sur-face deformation monitoring and topographic profile reconstruc-tion. Moreover, atmospheric disturbances can strongly compro-mise the accuracy of the results. Decorrelation in Interferometric Radar Echoes (1992) Temporal|) are the main factors affecting the interferometric phase.
