🔍 Key Concepts

• Purpose of an ATR (often called TR or TR/ATR) box in a marine RADAR system • How a RADAR transmitter and receiver share the same antenna • What must happen to the receiver while the transmitter is generating a high‑power pulse

💭 Think About

• Think about what would happen to a very sensitive receiver if it were directly connected while the transmitter sends out a high‑power pulse. • Does the ATR box deal with protection, isolation, switching, or some combination of these? • Consider whether each option describes a separate function, or different ways of saying the same basic role in the system.

✅ Before You Answer

• Be clear on whether the ATR box is mainly about protecting the receiver, routing energy, or blocking signals in a certain direction. • Decide if the receiver is active or inactive during the transmit pulse in a typical pulse RADAR. • Check whether any choice describes an effect that doesn’t actually make sense physically in a shared-antenna RADAR system.
