Radar interference may occur when near another shipborne radar that is operating
in the same frequency band as your radar. Its on-screen appearance looks like

from the center to the edge of the display. Interference effects are distinguishable
from normal echoes because they do not appear in the same place on successive
rotations of the scanner.
