If you see a ghost on radar are you seeing boobsie?

If not what are you seeing, and how would you define a ghost?

Joe, I'm only answering because I know that it will really hurt you to give
me some points!


A Ghost is the image that appears on your radar screen as a result of the
signal that bounced off the real target, and then bounced off of your boat
before being bounced off the real target again.

I know that you weren't able to understand that explanation - so I'll have
another go. A Ghost is a false image on your Radar screen.

That may be one of the answers, but it is not the only answer .....
operator error and atmospherics, can also cause a "ghost".

Where did you get that line of BS Donal? Is that a yachtmaster physic explaination?

Thats not correct either.

Anyone else wanna try to provide the correct answer before I set Donal strait?

It is a "false" radar return due to the return path delay to the most
recent pulse not being c/d where c is the local speed of light and d
distance to the apparent target. This can arise from anything which
alters propagation and therefore the effective c between transmitter and
reflector. Ghost images have sometimes been incorrectly ascribed to
birds and rain but in fact these are usually real returns and not ghosts.

You're saying a ghost is real?

Good lord.

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

Sorry Bart,

You have over complicated and generalized a ghost. You are partly
correct but.....not completly correct.
