Definition

Microwave Radiance is the intensity of microwave radiation. In radiometery, Radiance refers to a measure of the intrinsic radiant intensity emitted by a radiator in a given direction. Radiance is measured in watts per square meter and steradian.
Microwave Radiation refers to electromagnetic radiation generally in the frequency range between 300 MHz and 300 GHz (free-space wavelengths between 1 and 1000 mm). Within these frequencies lie the UHF, SHF, and EHF radio frequency bands. Radars operate at microwave frequencies. Radiance is a radiometric term for the rate at which radiant energy in a set of directions confined to a unit solid angle around a particular direction is transferred across unit area of a surface (real or imaginary) projected onto this direction.
