You observe a target visually dead ahead but it is displayed on your RADAR at 5 degrees to the starboard of the heading flash. How would you correct this?

The key idea is azimuth alignment between the radar and the ship’s heading. If you see a target visually dead ahead but the radar shows it off to the starboard, the radar’s antenna azimuth isn’t aligned with the vessel’s heading reference. That offset (5 degrees) indicates the antenna pedestal is misaligned.

The best fix is to check the scanner for antenna misalignment and realign it so that the radar’s 0-degree bearing coincides with the ship’s heading. After realigning, verify with a known reference (a fixed landmark or a test target) to confirm that dead ahead on the water now appears dead ahead on the radar.

Restarting, changing gain, or recalibrating target speed won’t correct this bearing discrepancy, since the issue is a physical misalignment of the antenna, not a software or signal setting problem.
