We develop a new algorithm for interferometric Synthetic Aperture Radar (SAR) phase unwrapping based on the rst Green's identity with the Green's function representing a series in the eigenfunc-tions of the two-dimensional Helmholtz homogeneous diierential equation. This provides closed-form solutions using one-or two-dimensional Fast Fourier Transforms. The algorithm is elaborated using adapti...

Abstract Success of Interferometry Synthetic Aperture Radar (InSAR) technique for deriving digital elevation model (DEM) in the heavily vegetated humid tropic using Sentinel-1 SAR has been controversial, owing to difficulty achieving good coherence. Yet achievable coherence with over rarely reported. Consequently, this paper evaluates tropic. Twelve part Johor selected based on perpendicular an...

Interferometric coherence is an important indicator of reliability for interferograms obtained by interferometric synthetic aperture radar (Interferometric SAR, InSAR). Areas with low coherence values are unsuitable for interferometric data processing. Also, it may be used as a classification parameter for various coverage types. Coherence magnitude can be calculated as an absolute value of the...

This paper presents a comparative assessment of Synthetic Aperture Radar interferometric techniques (InSAR) that allow the detection of deformation models along the line-of-sight of the radar. Given the susceptibility of these methods to several limitations that act as noise effects in the interferograms, known as decorrelation phenomena, multi-temporal InSAR techniques have been used for the e...

We introduce the development of a robust ground-based synthetic aperture radar (GB-SAR) system capable of obtaining highly accurate SAR images of surface targets repeatedly by dedicated efforts for accurate motion control and innovative system design for stable RF acquisition. A brief introduction of the GB-SAR system and some test images will be followed by the accuracy assessment of the syste...

This paper introduces a new and novel radar interferometry based on Doppler synthetic aperture radar (Doppler-SAR) paradigm. Conventional SAR interferometry relies on wideband transmitted waveforms to obtain high range resolution. Topography of a surface is directly related to the range difference between two antennas configured at different positions. Doppler-SAR is a novel imaging modality th...
