The paper debates the impact of sensor configuration diversity on the crop classification performance. More specifically, the analysis accounts for multi-temporal and polarimetric C-Band SAR information used individually and in synergy with Multispectral imagery. The dataset used for the investigation comprises several multi-angle Radarsat-2 (RS2) fullpol(More)
In this paper we face one of the main issues in Ground-Based radar applications, i.e. the evaluation and removal of the atmospheric phase screen (APS). The time-varying delay statistics are assessed by means of both radars and meteo simulated datasets and are critically interpreted with particular reference to the entailed compensation issues. A(More)
The paper deals with the Atmospheric Phase Screen issue in Ground Based SAR interferometry. The ku-band RADAR used, the “IBIS” by IDS, is capable to continuously image scenes of a few square kilometers with a repeat interval that ranges from a small fraction of a second (in unfocused mode), up to a few minutes (in focused SAR mode). Such features allowed an(More)
Multipurpose small reservoirs are important for livelihoods in rural semi-arid regions. To manage and plan these reservoirs and to assess their hydrological impact at a river basin scale, it is important to monitor their water storage dynamics. This paper introduces a Bayesian approach for monitoring small reservoirs with radar satellite images. The newly(More)
A new ‘growing’ maximum likelihood classification algorithm for small reservoir delineation has been developed and is tested with Radarsat-2 data for reservoirs in the semi-arid Upper East Region, Ghana. The delineation algorithm is able to find the land-water boundary from SAR imagery for different weather and environmental conditions. As such, the(More)
In this work, a numerical method optimizer based on Covariance Matching is proposed for SAR polarimetric calibration. The method makes use of the information provided by a Distributed Target and a Corner Reflector in order to jointly estimate the system polarimetric distortion parameters and the Faraday Rotation. A preliminary analysis is conducted to show(More)
