What would most likely prevent a SART's signal from being detected?

🔍 Key Concepts

• SART operating frequency and which ship’s radar band can detect it • Difference between 3-cm (X-band) radar and 10-cm (S-band) radar • Whether sea conditions or the ionosphere affect SART detection at its operating frequency

💭 Think About

• Ask yourself: At what radar frequency does a SART respond, and which radar band on a ship matches that frequency? • Consider which of the choices would make the SART essentially invisible to the radar, rather than just making the echo weaker or more cluttered. • Think about whether the ionosphere has a major effect on the kind of short-range, line-of-sight radar used for SART detection.

✅ Before You Answer

• Verify the exact frequency/band a SART transmits on and match it to either 3‑cm or 10‑cm radar. • Check which factor would cause no response at all on the radar versus just reduced range or a less clear picture. • Confirm whether heavy sea swells mainly create sea clutter or actually prevent the radar from seeing a correctly matched SART signal.
