Coastal environments are dynamic ecosystems, constantly subject to erosion/accretion processes. Erosional trends have unfortunately been intensifying for decades due to anthropic factors and an accelerated sea level rise might exacerbate the problem.

In multitemporal synthetic aperture radar (SAR) and polarimetric SAR (PolSAR), coherence is a capital parameter to exploit common information between temporal acquisitions. Yet, its use is limited to high coherences. This article proposes the analysi

Automotive radars can use the wide band at extremely high frequencies (EHF) between 30 GHz and 300 GHz, which has a higher amount of free frequency bands than the lower part of the electromagnetic spectrum. The focus of this thesis is to develop a ho

Soil permittivity estimation using Polarimetric Synthetic Aperture Radar (PolSAR) data has been an extensively researched area. Nonetheless, it provides ample scope for further improvements. The vegetation cover over the soil surface leads to a compl

A geometrical decorrelation constitutes one of the sources of noise present in Synthetic Aperture Radar (SAR) interferograms. It comes from the different incidence angles of the two images used to form the interferograms, which cause a spectral (freq

Microstrip patch antennas, introduced in the late 70s, are one of the most widely used printed antennas. Their light weight, small size, low profile, low cost, robustness and good radiation performance, makes them to be one of the preferred options f
