🔍 Key Concepts

• RADAR duplexing – how a single antenna is used for both transmitting and receiving • Role of the TR (Transmit-Receive) box in protecting sensitive receiver components • Difference between blocking high‑power transmit pulses and muting/blanking the receiver

💭 Think About

• When the radar is transmitting, what happens to the power level in the waveguide, and what would that do to an unprotected receiver front end? • Does the TR box mainly affect the transmitter, the receiver, or both? Think about which one is more fragile. • Why might it be useful for the receiver not only to be protected from high power, but also to be momentarily unable to hear weak echoes during the transmit pulse itself?

✅ Before You Answer

• Identify which choice(s) mention protecting the receiver from strong radar pulses and which mention affecting the receiver’s operation (muting/turning off). • Ask: does the TR box’s function include anything about preventing received signals from entering the transmitter, or is its main concern the receiver side? • Look for the option that best matches both the protection function during high‑power transmission and the short, timed effect on the receiver each time the magnetron fires.
