Rain or snow clutter
Radar detects rain and snow. Returns from storm areas and rain squalls consist of
countless small echoes which continually change in size, intensity and position.
These returns sometimes appear as large hazy areas, depending on the intensity of
the rainfall or snow in the storm cell.
Mutual radar interference
This can occur when two or more radar-equipped vessels are operating within range
of each other. The interference usually appears as a spiral of small dots from the
display centre, and is most marked at long ranges.
