Which calibration type focuses on horizontal angular alignment?

• A. Azimuth calibration
• B. Elevation calibration
• C. Range calibration
• D. Time synchronization

Answer: (A)

Horizontal angular alignment is about getting the bearing in the horizontal plane correct. This is what azimuth refers to—the angle around the vertical axis that tells you where the antenna is pointed relative to a reference direction. Calibrating azimuth ensures the system’s horizontal pointing direction matches the true bearing to targets. Elevation calibration, by contrast, handles the vertical tilt or up/down angle. Range calibration checks distance accuracy, and time synchronization aligns timing across systems. So the calibration that focuses on horizontal angular alignment is azimuth calibration.
