A new interpretation of multifrequency/multipolarization radar signatures of the Gulf Stream front

open access: yes, 1999
Radar signatures which are observed on SIR-C/X-SAR multifrequency/multipolarization synthetic aperture radar images of the Gulf Stream off the U.S. east coast are compared with results of simulations with a numerical radar imaging model. Based on in situ

Stochastic simulation experiment to assess radar rainfall retrieval uncertainties associated with attenuation and its correction [PDF]

open access: yes, 2008
As rainfall constitutes the main source of water for the terrestrial hydrological processes, accurate and reliable measurement and prediction of its spatial and temporal distribution over a wide range of scales is an important goal for hydrology.

The radar signature of the Wind Lens: a less disruptive wind turbine? [PDF]

open access: yes, 2012
We study the radar signature of a new type of wind turbine, named the Wind Lens. This design includes a flanged shroud around the turbine which concentrates the wind flow past the turbine blades and hence improves the efficiency.

Proof of Feasibility of the Sea State Monitoring from Data Collected in Medium Pulse Mode by a X-Band Wave Radar System

open access: yesRemote Sensing, 2018
X-band marine radars can be exploited to estimate the sea state parameters and surface current. However, to pursue this aim, they are set in such a way as to radiate a very short pulse to exploit the maximum spatial resolution.
