Which of the following is NOT a step in performing a radar sweep for a search pattern?

• A. Rotate the Antenna Manually 90 Degrees
• B. Set Appropriate Scan Rate
• C. Monitor for Contacts
• D. Apply Gating

Answer: (C)

In a radar sweep for a search pattern, the actions are about configuring and moving the beam to cover the area. Rotating the antenna to sweep across different sectors is a direct way to change where the beam points and ensure full coverage. Setting an appropriate scan rate is essential because it determines how quickly the beam moves and how often each area is refreshed on the display, balancing coverage with resolution. Applying gating is a technique used to filter or gate echoes so the system focuses on plausible targets and reduces clutter, making the sweep results more reliable.

Monitoring for contacts, while it happens during radar operation, is not a step thatSet up or execute the sweep itself. It’s the ongoing observation of what the radar displays as the sweep occurs, rather than a procedural step used to perform the sweep. So the action that isn’t a step in performing the sweep is monitoring for contacts.
