—Efficient estimation of the interferometric phase and complex correlation is fundamental for the full exploitation of interferometric synthetic aperture radar (InSAR) capabilities. Particularly, when combining interferometric measures arising both from distributed and concentrated targets, the interferomet-ric phase has to be correctly extracted in order(More)
—There is a need for scattering models that link quantitatively SAR interferometric observables to soil moisture. In this work we propose a model based on plane waves and the Born approximation, deriving first the vertical complex wavenumbers in the soil as a function of geometrical and dielectric properties and successively the complex interferometric(More)
For spaceborne SAR (Synthetic Aperture Radar) systems, the dispersive effects of the ionosphere on the propagation of the SAR signal can be a significant source of phase error. While at X-band frequencies the effects are small, current and future P-, Land C-band systems would benefit from ionospheric compensation to avoid errors in topographic retrieval. In(More)
1. ABSTRACT Many urban areas in China are affected by land subsidence. The Permanent Scatterers (PS) technique [1], [2] is a powerful tool for monitoring terrain motions by means of space-born radar data on a large number of coherent targets. Core idea of the PS technique is the exploitation of a high density of measure points (usually but not necessarily(More)
