The RADARSAT Synthetic Aperture Radar (SAR) antenna is a large (1.5m × 15m) slotted waveguide planar array operating at 5.3 GHz. The antenna comprises 32 slotted waveguide rows, and is mechanically divided into 4 panels to enable stowage during launch. Each waveguide row is fed by a 1-to-8 azimuth power dividing network (APDN). The 32 rows of the APDN are excited across the 1.5m dimension by the elevation...
This study evaluates the potential of wavelet-based texture modeling for the classification of stand age in a managed maritime pine forest using very high resolution satellite data. A cross-validation approach based on stand age reference data shows that multivariate modeling of the spatial dependence of wavelet coefficients outperforms the use of features derived from co-occurrence matrices. Simultaneously...
extural analysis can bring valuable information in the classification or the segmentation process of land covers displaying regular patterns in very high resolution remotely sensed images. In this study, we investigate how features extracted by multivariate modeling of the local spatial dependence in the wavelet domain can efficiently capture the textural content of maritime pine forest images in...
The limitation of the detection rate of standard bakelite resistive plate chambers (RPC) used as muon detector in LHC experiments is behind the absence of such detectors in the high η regions in both CMS and ATLAS detectors. RPCs made with low resistivity glass plates (1010 Ω.cm) could be an adequate solution to equip the high η regions extending thus both the trigger efficiency and the physics performance...
