Record 4 2007-03-11

English

Subject field(s)
  • Spacecraft
  • Remote Sensing
DEF

A scanner with an oscillating mirror that moves back and forth across the satellite's direction of travel, creating scan line strips that are contiguous or that overlap slightly.

CONT

One type of scanner is called a whiskbroom scanner also referred to as across-track scanners. It uses rotating mirrors to scan the landscape below from side to side perpendicular to the direction of the sensor platform, like a whiskbroom. The width of the sweep is referred to as the sensor swath. The rotating mirrors redirect the reflected light to a point where a single or just a few sensor detectors are grouped together. Whiskbroom scanners with their moving mirrors tend to be large and complex to build. The moving mirrors create spatial distortions that must be corrected with preprocessing by the data provider before image data is delivered to the user. An advantage of whiskbroom scanners is that they have fewer sensor detectors to keep calibrated as compared to other types of sensors.

OBS

across-track scanner; whiskbroom scanner: terms officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Key term(s)
  • across track scanner
  • whisk broom scanner
  • whisk-broom scanner

French

DEF

Scanneur ayant un miroir oscillant dont le déplacement perpendiculaire à la trajectoire du satellite engendre des lignes de balayage contiguës ou légèrement chevauchantes.

OBS

dispositif de balayage transversal : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

Spanish

CONT

El sistema de escáner transversal utiliza un espejo rotativo, éste se encuentra conectado a un motor eléctrico cuyo eje de rotación es paralelo a la dirección de vuelo.

Record 5 2005-01-24

English

Subject field(s)
  • Radar, Radio Guidance and Goniometry
  • Spacecraft
  • Remote Sensing
DEF

Remote sensing systems that build up an image by scanning from side to side in a direction that is at right angles to the sensors direction of movement[;] this scanning from side to side is achieved through electromechanical mechanisms which change the direction of view of the sensor.

CONT

Spatial imaging is achieved using the push-broom principle: the across-track scanning is performed electronically and the along-track scanning is made thanks to the satellite motion.

OBS

Sensors aboard the Landsat satellites were built in a "whisk broom" (across track) configuration. In a whisk broom sensor, a mirror scans across the satellite's path, reflecting light into a single detector which collects data one pixel at a time. The moving parts make this type of sensor expensive and more prone to wearing out.

OBS

across-track scanning: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Key term(s)
  • cross-track scanning
  • across track scanning

French

Domaine(s)
  • Radar, radioguidage et radiogoniométrie

DEF

Scannage effectué par défilement du champ de visée instantané perpendiculairement à la trace de la plate-forme d'observation sur le sol.

OBS

Le «scannage transversal» peut être réalisé par des moyens mécaniques ou électroniques.
