Which RADAR subsystem generates and radiates the RF carrier?

• A. Generates and amplifies the RF carrier, modulates with intelligence, and radiates the signal.
• B. Receives RF energy and converts it to video.
• C. Directs the antenna toward targets and tracks them.
• D. Processes video signals for display.

Answer: (A)

The function being tested is the transmitter. It is the subsystem that creates the RF carrier, amplifies it to the required power, modulates it with the radar signal (such as pulsed envelopes or coded waveforms), and radiates it through the antenna. This is why it’s the correct choice: generation and emission of the carrier are the transmitter’s core duties. The other subsystems do not generate the carrier. The receiver handles capturing returned energy and converting it to a video signal for processing. The antenna system (often part of a separate tracking or pointing unit) directs the antenna to scan and track targets. The radar processor handles converting received video into display formats.
