A ghost image is a false image moving in parallel
of a real object being tracked. They tend to be
more of an arc shape or fuzzy in shape compared
to the sharper image or a real object.

They are formed by the signal taking a longer
path to the object. Most commonly from a reflection
off some other part of a larger vessel. This could
change the beam shape of the radar. Sometimes
you can get echos off thunderstorms.

Or perhaps your optical coupler has shorted out. grin
