Remote sensing

stereo model

Earth science; Remote sensing

Three-dimensional visual impression produced by viewing a pair of overlapping images through a stereoscope.

raster pattern

Earth science; Remote sensing

Pattern of horizontal lines swept by an electron beam across the face of a CRT that constitute the image display.

thermography

Earth science; Remote sensing

Medical applications of thermal IR images. Images of the body, called thermograms, have been used to detect tumors and monitor blood circulation.

antenna

Earth science; Remote sensing

Device that transmits and receives microwave and radio energy in radar systems.

Doppler shift

Earth science; Remote sensing

A change in the observed frequency of EM or other waves caused by the relative motion between source and detector. Used principally in the generation of synthetic-aperture radar images.

Describes a radar pulse in which the polarization of the return is the same as that of the transmission. Parallel-polarized images may be HH (horizontal transmit, horizontal return) or VV (vertical ...
