Determining Actual Radar Range
The actual maximum radar range is essentially line-of-sight, and is
limited by the height of the scanner and the height of the target as
shown below lists some range examples:
Radar Range
Antenna Height (m) Target Height (m) Maximum Range (nm)
3 3 7.8
3 10 10.9
5 3 8.9
5 10 12.0
Note: The ranges shown in the table are theoretical maximum
ranges. The radar horizon is greater than the optical
horizon, but the radar can only detect targets if a large
enough target is above the radar horizon.
