It is possible to detect a search object beyond the calculated sweep width.

• A. Not possible to detect beyond the calculated sweep width
• B. It is unlikely to detect beyond the calculated sweep width
• C. May be detected beyond the calculated sweep width
• D. It is possible to detect a search object beyond the calculated sweep width

Answer: (D)

Think of sweep width as a planning estimate, not a hard boundary. It represents the distance from a search path within which a target is expected to be detected with a specified probability under certain conditions. Because it’s based on averages and controlled assumptions, real-world factors can push actual detectability beyond that measured width.

If conditions are more favorable than assumed—target is highly visible, reflective, or stands out against the background; observers or sensors are exceptionally sensitive; or the target spends more time in view as the platform moves—detection can occur beyond the calculated sweep width. Overlaps between search lanes, different sensor modalities, and movement of the target can all extend the effective detection area.

So the statement that it is possible to detect a search object beyond the calculated sweep width aligns with how sweep width is used: a useful planning tool, not a strict cutoff.
