Which of the following radar exclusion zones are 100 M?

• A. Personnel-denied occupancy zone
• B. No-fly zone 100m
• C. Controlled access zone
• D. Safety buffer zone

Answer: (A)

Radar exclusion zones are safety radii around a radar that limit access to protect people from exposure and to keep the radar operating without interference. When a zone is defined specifically to keep people out within a fixed distance, it becomes the personnel-denied occupancy zone. This 100-meter boundary is all about ensuring that no personnel occupy the area right around the radar during operation, reducing exposure risk and hazards from the high-power emissions and equipment movement. The other zones serve different purposes: a no-fly restriction relates to aircraft and airspace rather than ground occupancy, a controlled access area governs who can enter but not necessarily at a fixed distance, and a safety buffer is a general precaution that can vary and isn’t necessarily tied to a specific 100-meter occupancy rule. So the 100-meter zone targeted at preventing people from occupying the area around the radar is the personnel-denied occupancy zone.
