Remote sensing
Signal to noise radio (S/N)
Earth science; Remote sensing
The ratio of the level of the signal carrying real information to that carrying spurious information as a result of defects in the system.
Radar scatterometer
Earth science; Remote sensing
A non-imaging device that records radar energy backscattered from terrain as a function of depression angle.
Oblique photograph
Earth science; Remote sensing
Photograph acquired with the camera intentionally directed at some angle between horizontal and vertical orientations.
Kinetic energy
Earth science; Remote sensing
The ability of a moving body to do work by virtue of its motion. The molecular motion of matter is a form of kinetic energy.
Artefact
Earth science; Remote sensing
A feature on an image which is produced by the optics of the system or by digital image processing, and sometimes masquerades as a real feature.
Index of refraction (n)
Earth science; Remote sensing
Ratio of the wavelength or velocity of electromagnetic radiation in a vacuum to that in a substance.
