Subject field(s)
  • Remote Sensing
DEF

The ratio of maximum measurable signal to minimum detectable signal.

CONT

[The] dynamic range [is] the range of radiances over which instruments and sensors are sensitive. The upper end of the dynamic range is the saturation radiance. The lower end is the noise floor, i.e., the radiance corresponding to the low radiance noise level of the instrument. These radiances may be expressed as equivalent blackbody temperatures for thermal bands.

OBS

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

French

Domaine(s)
  • Télédétection
CONT

La gamme dynamique correspond au rapport du signal mesurable maximal sur le signal mesurable minimal. La limite supérieure fait habituellement référence à l'intensité de saturation et la limite inférieure au bruit.

DEF

The range of signal amplitudes from the loudest to the quietest that can be reproduced effectively by an equipment.
