🔍 Key Concepts

• Radar SART (Search and Rescue Transponder) operation and its appearance on 3-cm (X-band) radar • Difference between SART, EPIRB, and survival craft equipment • What a radar fault usually looks like compared to a distinct pattern of concentric circles

💭 Think About

• On which radar band (3‑cm or 10‑cm) does a SART produce its characteristic display, and what does that pattern look like to the observer? • Would a radar equipment fault normally produce a neat, centered series of regular circles, or more random/erratic symptoms? • Which device is specifically designed to be detected and displayed on X‑band radar: EPIRB, SART, or something else on a survival craft?

✅ Before You Answer

• Verify which equipment produces concentric circles or dots/lines centered on your own-ship position on 3‑cm radar. • Confirm whether an EPIRB is detected by satellites, radar, or both, and how (or if) it appears on a radar screen. • Consider if the question’s wording "your own vessel" changes which option makes sense compared with a survival craft at some distance.
