RADARSAT-2, Canada's next generation earth observation satellite, is co-funded by the Canadian Space Agency(CSA) and MacDonald Dettwiler... The imaging sensor on the satellite is a C-band Synthetic Aperture Radar(SAR) capable of operating in a wide variety of imaging modes. All imaging modes of the current RADARSAT-1 satellite will be provided, as well as some new modes that incorporate important innovations and improvements. The horizontal co-polarization(HH) of RADARSAT-1 will be supplemented by options for vertical co-polarization(VV) and cross-polarization(HV or VH), and there will be new Quad-Polarization modes providing fully polarimetric data sets. The other major new mode is referred to as Ultra-Fine, providing swath imaging with resolution of about 3 m in each dimension. Re-visit times will be reduced since all imaging modes will be available either to the left or right sides of the satellite track. 3, record 1, English, - imaging%20sensor

Les systèmes embarqués à bord des satellites comportent de multiples instruments dont les fonctions sont variées. Toutefois, pour une mission donnée, les instruments de la charge utile ont des fonctions bien particulières. Il s'agit le plus souvent de capteurs qui ont pour vocation d'effectuer des mesures du rayonnement émis ou rémis par la Terre, l'atmosphère ou divers objets de l'Univers, ou bien de dispositifs de réception et de réémission de signaux, quand il s'agit de missions de télécommunications, par exemple. Deux grandes familles de capteurs sont identifiables : les capteurs non-imageurs et les capteurs-imageurs, ces derniers restituant sous forme d'images les observations effectuées dans un champ donné. Les principales caractéristiques d'un capteur-imageur sont : - le champ d'observation total (de quelques dizaines à quelques millions de km) [;] - la résolution spatiale (qui exprime son aptitude à distinguer les détails dans le champ total d'observation) [;] - les bandes spectrales (domaines de sensibilité spectrale des détecteurs et de leurs accessoires (filtres...] [;] - la résolution radiométrique (qui caractérise l'aptitude des détecteurs à distinguer des signaux porteurs de plus ou moins d'énergie). 4, record 1, French, - capteur%20imageur

RADARSAT-2 offers three polarimetric modes: (1) selective polarization (dual pol) providing one co-pol channel (HH or VV) and the corresponding cross-pol channel (HV); (2) high resolution (3 m) single pol channel (HH or VV or HV); and (3) a fully polarimetric mode (quad pol) providing both amplitude and phase. The fully polarimetric mode is significant since RADARSAT-2 is the first commercial satellite to offer this mode. 5, record 2, English, - polarization%20mode

On peut utiliser les termes «polarisation en quadrature» et «polarimétrie intégrale» comme synonymes de «polarimétrique». La mesure de la phase relative entre les canaux constitue un paramètre très important pour un radar polarimétrique, alors qu'elle n'est pas obligatoirement mesurée pour les autres types de radar. On trouve sur le satellite ENVISAT un mode de polarisation alternée, pour lequel la phase relative est mesurée. Cependant, la phase principale HH-VV n'y a aucune signification en raison du délai entre les mesures. 5, record 2, French, - mode%20de%20polarisation

The SAR contains sophisticated electronics that feed a state-of-the-art distributed active phased-array antenna consisting of 512 transmit/receive modules(TRMs) with radio frequency(RF) and power distribution networks. Each TRM feeds a dual-polarization patch radiated subarray. This provides increased flexibility and capability over other commercial SAR remote sensing satellites. Thus, RADARSAT-2 will offer high quality products, including selectable polarization and fully polarimetric data, ultra-fine images with spatial resolution of 3 m, and a moving object detection experiment(MODEX) imaging mode. 2, record 3, English, - transmit%2Freceive%20module
