Virtual image 

The image of a large physical object in a close proximity may appear in two different orientations. One 
is a real image and the other is a false image caused by wave reflected on the chimney stack or the 
mast, etc. 
On the display, one image appears with a right distance and bearing, and another one appears in the 
direction of chimney stack, mast, etc. These images may also be generated by being reflected multiple 
times from the bridges and quays too.

Duplicate target images 

When there is a big reflective surface nearby and perpendicular at a close distance (i.e. when your ship 
is passed by a big ship, etc.) radio wave bounces repeatedly between your ship and the other ship. 
Therefore, 2 to 4 images may appear at equal range in the direction of this target. The false image 
generated by this multi-path reflection is referred as “double targets”. In this case, the closest target is 
the real one. 
Even if the double targets appear, if the distance and bearing between own ship and the reflective 
target changes, the duplicate targets will disappear. Therefore, this false image can be easily 
distinguished.
