What is the purpose of the RADAR Processor?

• A. Unit that decides which is the stronger video that is indicated to the RF distribution subassembly so that it may cause the transmitted reply to be radiated from the same antenna.
• B. Filters noise from received signals.
• C. Amplifies the RF carrier for transmission.
• D. Displays target video on a monitor.

Answer: (A)

The radar processor’s job is to choose the best, strongest video signal from the radar’s inputs and feed that decision to the RF distribution path so the transmitter uses the same antenna for both transmit and receive. By selecting the strongest video, it ensures the most reliable target information is sent through the system and that the radar’s duplex path remains coherent, keeping the transmit and receive paths aligned on the same antenna. This function isn’t about filtering noise, which happens in the receiver front end, nor about amplifying the RF carrier, which is a transmitter task, and it isn’t primarily about displaying video, which is a display/vision function—though the processor’s selected video can be used for display as well.
