(CARRIER FREQUENCY)—The frequency of the unmodulated output of a transmitter [18].

Equipment that selectively transfers remote station functions and signals to transmitters [17].

The device used to send the transmitted signal energy into space [10].

Those substances, such as glass, that pass almost all of the light waves falling upon them [10].

A waveguide mode in which the entire electric field is perpendicular to the wide dimension and the magnetic field is parallel to the length. Also called the TE mode [11].

A waveguide mode in which the entire magnetic field is perpendicular to the wide dimension and some portion of the electric field is parallel to the length. Also called the TM mode [11].

The up and down motion of a wave as the wave moves outward [10].

(BEARING) SIGNAL—In a monopulse radar system, the combination of individual lobe signals that represents target-offset direction and amplitude from the antenna axis [18].

The band of frequencies from 300 gigahertz to 3,000 gigahertz.

A three-terminal device that is similar to two SCRs back to back with a common gate and common terminals. Although similar in construction and operation to the SCR, the triac controls and conducts current flow during both alternations of an ac cycle [7].
