When the height of own ship’s scanner is 10 m for instance,
i. A target that can be detected at the radar range of 64 nm on the radar display
is required to have a height of 660 m or more.
ii. If the height of a target is 10 m, the radar range has to be approx. 15 nm.

radar display depends upon the size of the target and the weather conditions,
