perpendicular to the beam cannot be seen by the radar. Therefore, strong winds blowing strictly from left to right or from right to left, relative to the radar, can not be detected.)RadianceA measure of the intensity of the radiant energy flux ...
shortwave radianceA measure of the intrinsic radiant energy flux intensity, at wavelengths between 0.4 and 4 µm, emitted by a radiator in a given direction, expressed in units of energy per unit time per unit solid angle.
A measure of the intensity of the radiant energy flux emitted by a body in a given direction.
