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


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.
