COMPONENT PRINCIPLES OF OPERATION. (CONT)
AZIMUTH AND ELEVATION ANTENNAS
The azimuth and elevation antenna reflectors are used to shape and direct the pulsed rf energy from the receiver-
transmitter. The pulsed rf energy from the transmitter leaves the antenna horn and strikes the antenna reflector. The
antenna reflector reflects the rf energy out in the form of a narrow beam. When this beam strikes a target, a portion of
the beam Is reflected back toward the antenna. The reflected beam, which is called an echo, then strikes the antenn'a
reflector an used to produce an image on the crt that represents the target.
