Microwave Imaging Radiometer with Aperture Synthesis (MIRAS) is the major instrument on the Soil Moisture and Ocean Salinity satellite (SMOS). MIRAS employs a planar antenna composed of a central body (the so-called hub) and three telescoping, deployable arms, in total 69 receivers on the Unit. Each receiver is composed of one Lightweight Cost-Effective Front-end (LICEF) module, which detects radiation in the microwave L-band, both in horizontal and vertical polarizations. The aperture on the LICEF detectors, planar in arrangement on MIRAS, point directly toward the Earth's surface as the satellite orbits. The arrangement and orientation of MIRAS makes the instrument a 2-D interferometric radiometer that generates brightness temperature images, from which both geophysical variables are com

dbo:abstract
  • Radiòmetre de Microones amb Síntesi d'Obertura (en (anglès) Microwave Imaging Radiometer with Aperture Synthesis, MIRAS ) és l'instrument principal en el satèl·lit SMOS de l'ESA. MIRAS és un radiòmetre d'apertura de síntesi per interferometria distribuït en un espai bidimencional en forma de 'Y'. L'objectiu d'aquest instrument és mesurar la radiació emesa espontaneament per la terra per a poder estimar la salinitat dels oceans i la humetat del sòl. Consta dúna una antena plana composta d'un cos central i tres telescòpics, braços desplegables, un total de 69 receptors. Cada receptor es compon d'un mòdul LICEF, que detecta la radiació en l'espectre de microones, específicament a la banda L, tant en polaritzacions horitzontal i vertical. L'obertura dels detectors LICEF, plana en la disposició sobre MIRAS, apunten directament cap a la superfície de la Terra com les òrbites dels satèl·lits. La disposició i l'orientació de MIRAS fa que l'instrument d'un 2-D interferomètric radiòmetre.El contractista principal instrument MIRAS va ser EADS-CASA Espacio, la fabricació de la càrrega útil de SMOS sota contracte de l'ESA.

The arrangement and orientation of MIRAS makes the instrument a 2-D interferometric radiometer that generates brightness temperature images, from which both geophysical variables are computed. The salinity measurement requires demanding performance of the instrument in terms of calibration and stability. The MIRAS instrument's prime contractor was EADS CASA Espacio, manufacturing the payload of SMOS under ESA's contract. (en)
