🔍 Key Concepts

• PFN (Pulse Forming Network) operation in a radar set • How a magnetron is keyed or turned on/off in typical marine radar • Difference between continuous and pulsed transmission in radar

💭 Think About

• Ask what a PFN actually does to the high-voltage output feeding the magnetron: does it create a steady signal or short bursts? • Consider how marine navigation radars avoid interfering with other users and measure range—do they send out a constant signal or short, timed transmissions? • Think about which type of modulation best describes turning the transmitter on and off for very short intervals.

✅ Before You Answer

• Verify that PFN stands for Pulse Forming Network and what that implies about the waveform shape. • Recall that a magnetron in typical shipboard radar is not run continuously, but is usually keyed in short intervals. • Match this behavior with the choice that describes transmitting energy in discrete, timed portions rather than a continuous carrier.
