Microwave sensors are particularly effective for measuring land surface hydrological parameters. Since microwave sensors enable us to observe ground surfaces both day and night, we can observe hydrologic phenomena that show remarkable diurnal variation. Further, an inherent feature of a microwave sensor lies in its wavelength between 1 mm and 1 m (0.3 to 300 GHz of frequency), making it possible to conduct observations without influence from weather and to detect the scattering information not only at the surface, but also in the volume. Furthermore, we can directly observe liquid water having larger relative permittivity than other physical parameters because the scattering of microwaves heavily depends on relative permittivity. There are two types of microwave sensors: a passive microwave sensor that observe weak microwave signals naturally radiated from the Earth’s surface, and an active microwave sensor that measures the backscattering coefficient of the transmitted beam.

microwave sensor: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Key term(s)
  • micro-wave sensor

CONT

Tous les objets reflètent, absorbent ou émettent un rayonnement électromagnétique qui correspond à leur composition et à leur structure. Un capteur hyperspectral, fonctionnant à l'aide du rayonnement solaire réfléchi, détecte les spectres particuliers, autrement dit la «signature spectrale» d'un objet, ce qui permet ensuite d'en déterminer la composition.

OBS

capteur hyperspectral : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

Micro Robotic Sensors. MCWL working with DARPA, ONR, and NRL to develop more robotic sensors capable of providing intelligence and accurate real time targeting. Desired Characteristics : Multi-spectral micro sensors that detect and track hostile forces thereby enabling an important RSTA function [;] Network centric micro sensor system capable of providing accurate intelligence and targeting data in an assigned battlespace.

Autre étape à franchir : des micro-détecteurs travaillant dans l'infrarouge et le visible et capables de tenir dans un volume inférieur à 1 cm³ ont déjà été réalisés par le CEA et le Leti. Mais leur intégration sur nanodrones va contraindre à gagner encore un ordre de grandeur sur la miniaturisation.

  • Appareils de cuisson des aliments
CONT

Le palpeur dont sont munies les cuisinières à plaques-fonte Frigidaire contrôle la température chaque microseconde. (...) La chaleur est distribuée uniformément à travers la fonte, éliminant les points chauds.

OBS

«cuisinière à éléments solides» : Selon les Services linguistiques de Camco Inc., le terme «élément solide» est un calque de l'anglais et se trouve dans les sources traduites.
