Remote sensing

In radar usage this is the distance in the direction of radar propagation, usually to the side of the platform in an imaging radar system. The slant range is the direct distance from the antenna to ...

Complementary colours

Earth science; Remote sensing

Two primary colours of light (one additive and the other subtractive) that produce white light when added together. Red and cyan are complimentary colors.

Saturation

Earth science; Remote sensing

In the IHS system, represents the purity of color. Saturation is also the condition where energy flux exceeds the sensitivity range of a detector.

Dielectric constant

Earth science; Remote sensing

Electrical property of matter that influences radar returns. Also referred to as complex dielectric constant.

Trade-off

Earth science; Remote sensing

As a result of changing one factor in a remote sensing system, there are compensating changes elsewhere in the system; such a compensating change is known as a trade-off.
