This paper proposes a method for improving the estimation accuracy of vegetation height using multi-baseline Polarimetric Interferometric Synthetic Aperture Radar (Pol-InSAR) data. Single-baseline Pol-InSAR technique has been applied to retrieve the vegetation parameters based on the random volume over ground (RVoG) model. There are two main error sources which might decrease the estimation acc...

Synthetic Aperture Radar (SAR) systems normally record both the amplitude and the phase of the backscattered echoes. However, the phase of a single backscattered image is of no use and therefore, conventionally the amplitude or intensity image is usually provided to the user. But on the contrary, the phase difference of two backscattered SAR images of the same area on the ground taken at slight...

A field campaign was carried out in the framework of the Mitigation of Electromagnetic Transmission errors induced by Atmospheric Water Vapour Effects (METAWAVE) project sponsored by the European Space Agency (ESA) to investigate the accuracy of currently available sources of atmospheric columnar integrated water vapor measurements. The METAWAVE campaign took place in Rome, Italy, for the 2-wee...

The integrity and reliability of levees, earthen dams and flood-control infrastructure are essential components of homeland safety. The development of a potentially affordable satellite-based interferometric synthetic aperture radar (InSAR) technique for use in a new health assessment framework to monitor, manage and ensure the safety of levees and other systems of flood-control infrastructure ...

Interferometric synthetic aperture radar (InSAR) methods and applications for mapping and monitoring displacements on mountain slopes and subsidence in urban areas were investigated in the EC project MUSCL (Monitoring Urban Subsidence, Cavities and Landslides by means of remote sensing) using various techniques. The area-extended differential InSAR technique was applied for mapping slow slope m...

[1] We use interferometric synthetic aperture radar (InSAR) and broadband seismic waveform data to estimate source parameters of the 29 June 1992, Ms 5.4 Little Skull Mountain (LSM) earthquake. This event occurred within a geodetic network designed to measure the strain rate across the region around Yucca Mountain. The LSM earthquake complicates interpretation of the existing GPS and trilaterat...

Synthetic aperture radar (SAR) is a coherent active microwave imaging method. In remote sensing it is used for mapping the scattering properties of the Earth’s surface in the respective wavelength domain. Many physical and geometric parameters of the imaged scene contribute to the grey value of a SAR image pixel. Scene inversion suffers from this high ambiguity and requires SAR data taken at di...

There has been increasing interest over the last few years in the use of radar interferometry for land subsidence evaluation/monitoring. InSAR time series algorithms such as PSI and small baseline methods offer the possibility to measure ground displacements to a degree of accuracy comparable to traditional geodetic technique such as leveling. This preliminary work reveals the potential of time...

A coherent scattering model for tree canopies is employed in order to characterize the sensitivity of an interferometric SAR (INSAR) response to the physical parameters of forest stands. The concept of an equivalent scatterer for a collection of scatterers within a pixel, representing the vegetation particles of tree structures, is used for identifying the scattering phase center of the pixel w...

Information about the shape of the Earth’s surface is important in many applications as it helps users to visualize and analyze geographic problems accurately in 3D. This paper focuses on the InSAR technique of generating Digital Elevation Models (DEM) by using InSAR data acquired from an airborne platform. The data cover a study area of 4 km x 3 km located in Thetford Forest, East Anglia, Unit...
