🔍 Key Concepts

• Function of an ATR (Automatic Transmit-Receive) box in a marine RADAR system • How a RADAR transmitter and receiver share the same antenna • How sensitive receiver components are protected from high-power transmitter pulses

💭 Think About

• Think about what happens to the RADAR receiver when the transmitter sends a very strong pulse through the same antenna. • Consider whether the ATR box only does one job (like blocking a signal) or if it has multiple related protection/switching functions. • Ask yourself: during transmission, what must happen to the receiver path, and during reception, what must happen to the transmitter path?

✅ Before You Answer

• Verify whether the ATR's primary job is switching the antenna between transmit and receive modes, or doing something else. • Check if protecting the receiver from strong transmitter pulses is the same thing as turning it completely off, or if there’s a difference. • Confirm if each individual statement (A, B, C) correctly describes an ATR function; only then decide if “All of the above” can be true.
