Which radar subassembly is used to convert weak returning signals into displayable video?

• A. Antenna
• B. Modulator
• C. Receiver
• D. Power Supply

Answer: (C)

Converting faint radar returns into a displayable picture happens in the stage that processes the incoming radio signals and turns them into a video waveform. This is the receiver. It first boosts the weak echoes with a low-noise amplifier, then down-converts and filters them through intermediate and baseband stages, and finally detects and shapes the signal into a video form that can be shown on the display. The antenna is responsible for capturing and transmitting RF energy, not converting it into video. The modulator controls the timing and shape of the transmitted pulses, not the processing of received echoes. The power supply simply provides power to the system. So the receiver is the part that makes the weak returns into usable video.
