2.5.4 Ghost Echoes
The ghost echoes may appear if there is a target having a wide smooth surface near
your own ship. As shown in Figure 2-9, the appearance of the ghost echoes is similar
to that of the indirect echoes.
The ghost echoes appear on the screen as if you saw the target reflected in a mirror.
