🔍 Key Concepts

• Basic components of a marine RADAR (transmitter, receiver, antenna, display) • The type of microwave tube typically used to generate short, high‑power RF pulses in radar • Differences between devices used in radar transmitters versus those used more in amplifiers or switching

💭 Think About

• Which of the listed devices is most commonly associated with generating high‑power microwave pulses in practical marine radar sets? • Can you recall which device name you have seen in radar specifications or manuals for small‑craft or shipboard radar? • Of the four options, which is most widely known and standardized for marine navigation radar rather than lab or specialized systems?

✅ Before You Answer

• Verify which device is specifically known as a microwave pulse generator for radar systems. • Check which options are more commonly used as RF amplifiers rather than primary transmitters. • Eliminate any components that are mainly switching tubes or power-control devices, not primary radar transmitters.
