Gain

(Redirected from Gain factor)



gain

An increase or amplification.

There are two general uses of the term in radar meteorology: 1) antenna gain (or gain factor), which is the ratio of the power transmitted along the beam axis to that of an isotropic radiator transmitting the same total power; and 2) receiver gain (or video gain), which is the amplification given a signal by the receiver.
