Duplicate target images

When there is a big reflective surface nearby and it is perpendicular at a close distance (i.e. when your

ship is passed by a big ship, etc.), the radio wave bounces between own ship and the other ship.

Therefore, two to four images may appear at equal range in the direction of this target. The false

images generated by this multi-path reflection are referred to as “double targets”. In this case, the

closest target is the real image.

If the distance and bearing between own ship and the reflective target changes, then the duplicate

targets will disappear. Therefore, this false image can be easily distinguished.

Own ship

Large vessel

Side lobe images

The microwave beam radiated from the antenna has a side lobe in different direction than that of the

main beam. Since this side lobe level is lower than that of main beam, the effect is negligible for targets

at long range, but a close, strong reflecting target may cause false image appearing in a circular arc

shape.

CAUTION

When own ship is close to large targets such as land, a

circular image may appear.
