Electronics (Mike Jaroch)

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].

A special type of monopole antenna array [17].

A short pulse, either positive or negative, that can be used to cause an electronic function to take place [9].

See SYNCHRONIZER [18].

In radar, pulses that are used to initiate specific events [18].

A three-electrode electron tube containing a plate, a cathode, and a control grid [6].

The part of a circuit breaker that senses any overload condition and causes the circuit breaker to open the circuit [3].
