Q

The modulation frequency of most RADAR systems is between:

🔍 Key Concepts

• Pulse Repetition Frequency (PRF) in marine radar systems • Typical audio-frequency range used for modulation/control circuits • Relationship between too low vs too high modulation frequency and target detection/clarity

💭 Think About

• Think about what frequency range is practical for timing circuits that control radar pulses on standard marine equipment. • Consider which of the options falls into a range commonly used for repetitive control signals, not for radio transmission itself. • Ask yourself which ranges would be too low (causing very slow sweeps and poor target update) or too high (creating unnecessary complexity for typical marine radars).

✅ Before You Answer

• Be clear that this question is about modulation (pulse repetition) frequency, not the microwave carrier frequency (which is in GHz). • Compare each choice to the typical audio and low‑kHz ranges used in other timing/modulation systems. • Eliminate any ranges that would obviously be impractical for stable timing circuits in older as well as modern marine radars.
