Due to the climate change situation, water deficit stress is becoming one of main factors that threatens agricultural sector in semi-arid zones. Thus, it extremely important provide efficient tools monitoring and early detection. To do so, a set Synthetic Aperture Radar (SAR) backscattering interferometric SAR (InSAR) Sentinel-1 data, covering period from January June 2016, are considered over ...

This paper discusses the use of modern 2D spectral estimation algorithms for synthetic aperture radar (SAR) imaging. The motivation for applying power spectrum estimation methods to SAR imaging is to improve resolution, remove sidelobe artifacts, and reduce speckle compared to what is possible with conventional Fourier transform SAR imaging techniques. This paper makes two principal contributio...

A new approach to tropical forest biomass monitoring with airborne interferometric X and P-band synthetic aperture radar (SAR) data is presented. Forest height, basal area, and aboveground biomass are modeled from remote sensing data for a study site in the Brazilian Amazon. Radar data quality has improved: A novel digital model of vegetation height from Xand P-band interferometry is available ...

Includes numerous up-to-date examples real from spaceborne platforms possibility to use a software support lecture practicals. Reviews theoretical principles an intuitive way for each application topic. Covers depth five domains (fo...

Interferometric synthetic aperture radar (InSAR) time series methods estimate the spatiotemporal evolution of surface deformation by incorporating information from multiple SAR interferograms. While various models have been developed to describe the interferometric phase and correlation statistics in individual interferograms, efforts to model the generalized covariance matrix that is directly ...

This work presents the first experimental demonstration of the virtual bandwidth synthetic aperture radar (VB-SAR) imaging scheme. VB-SAR is a newly-developed subsurface imaging technique which, in stark contrast to traditional close-proximity ground penetrating radar (GPR) schemes, promises imaging from remote standoff platforms such as aircraft and satellites. It specifically exploits the dif...

In this paper, a new function model for determining the minimum and maximum detectable deformation gradient in synthetic aperture radar interferometry (InSAR) with Envisat ASAR images is developed. The model incorporates the parameters of both interferometric coherence and multilook operator for 1, 5 and 20, rather than the interferometric coherence only in previous studies. Experimental result...
