Passive microwave radiometers can be grouped into two categories: conical scanning radiometers and cross-track scanning radiometers. A passive microwave radiometer is considered a conical scanning radiometer when the footprint size and earth incidence angle remain unchanged across the scan line, while a cross-track scanning radiometer has varying footprint size and earth incidence angle across the scan line.  4, record 1, English, - conical%2Dscanning%20radiometer

Conical scanning radiometers are characterized by a continuous instrument calibration, with the sensors passing, at every rotation, below two calibration sources: a cold-sky reflector ... and an on-board calibration target (OBCT) which provides a hot temperature reference.  5, record 1, English, - conical%2Dscanning%20radiometer

In weather radar, the name is sometimes applied to horizontal scanning because the surface swept in space by the beam as the antenna rotates in azimuth with fixed elevation angle, is a cone.  2, record 3, English, - conical%20scanning

Le balayage est conique lorsque les directions d’observation au cours d’un balayage sont situées sur un cône. On obtient un balayage conique quand l'axe du miroir est vertical dans l'avion ou le satellite et qu'il est en plus perpendiculaire à l'axe optique du détecteur. [Le principal avantage de ce système de balayage] est que la distance entre le capteur et le terrain reste constante, [d’où les] dimensions constantes de la tache élémentaire au sol. Par contre, il génère des images à géométrie particulière parce que les systèmes de restitution et de traitement des images sont en général conçus pour les images obtenues par balayage linéaire.  3, record 3, French, - balayage%20conique

The Bragg Crystal Spectrometer (BCS) is designed to study plasma heating and dynamics during the impulsive phase of solar flares. It consists of two bent crystal spectrometers, BCS-A and BCS-B, that observe the H-like line complex of Fe XXVI, and He-like complexes of Fe XXV, Ca XIX and S XV. Each spectrometer consists of a double detector placed behind a pair of germanium crystals that diffract the incoming X-rays into the detectors. The two structures are mounted at the front of the Yohkoh spacecraft, on either side of the central panel, with a thermal filter mounted in front of each spectrometer. The crystal dispersion axes are oriented north-south.  2, record 5, English, - Bragg%2Dcrystal%20spectrometer

The Black Body Calibration Mechanism. The black body observations are performed at least once a day. The mechanism uses two black bodies: one having the ambient spacecraft temperature and one heated to about 50 K above it. First the black body at ambient spacecraft temperature is viewed, and forms the reference signal. Then the heated black body is viewed, and the temperature difference between both black bodies is used to obtain the response of the detectors. The obtained response is converted into counts and transmitted to earth.  4, record 6, English, - black%2Dbody%20calibration
