Q

RADAR interference on a communications receiver appears as:

🔍 Key Concepts

• RADAR pulse repetition and how it can create rhythmic interference in audio circuits • Difference between random noise (static) and regular, periodic signals • How pulsed RF energy from RADAR might sound if converted to audio

💭 Think About

• If a RADAR is sending out regular pulses, what kind of sound pattern would those pulses create in a nearby audio receiver? Random or predictable? • Which choice best matches something that comes and goes in a regular pattern, rather than being constant or purely random? • Think about what ‘static’ usually sounds like on a radio. Is that caused by periodic pulses or by many random tiny signals?

✅ Before You Answer

• Distinguish between random noise versus regular, repeating interference • Consider that shipboard RADAR is a pulsed transmitter, not a continuous audio-frequency signal • Match each option’s description (varying, steady, hissing, static) to how a pulsed signal would sound in headphones or a speaker
