received power


received power

[ri′sēvd ′pau̇·ər] (electromagnetism) The total power received at an antenna from a signal, such as a radar target signal. In a mobile communications system, the root-mean-square value of power delivered to a load which properly terminates an isotropic reference antenna.

echo signal

The radar energy returned to a radar by a target. The amount of this energy is called received power. Also called a video signal or a target signal.

target signal

The radar energy returned to a radar by a target. Also called an echo signal or a video signal. The amount of this energy is called received power. The size of the echo on the PPI (plan position indicator) is a direct function of the received power. See echo.
