(3) False echo caused by the side lobes 

(4) Shadow and dead angle 

 

 

When a boat passes near a large boat, radio waves
are repeatedly reflected between own boat and the
boat nearby, causing several echoes at regular
intervals to appear in the same bearing (Multiple
reflections). These false echoes produced by
multiple reflections are called multiple echoes. In this
case, the real target is the closest one. The multiple
echoes soon disappear when your boat moves from
the boat that caused the multiple reflections or, the
boat has changed her course. For this reason, the
true image can easily be identified. 

The radio beam emitted from a radar
antenna contains some residual smaller
beams on both sides of the main beam.
These components are called the side
lobes. A closely located target with high
reflectivity can be displayed as an arc
caused by the side lobes. To reduce these
false echoes, reduce the gain slightly or
apply A/C sea control. 

 

Height of antenna affects the short
range target detection. If the
antenna is mounted too high, the
radar beam may skip the target,
causing no echo detection. The
vertical beam width of the radar
antenna also affects the close range
detection.  

If the funnel, mast or other structures are located near a radar antenna, the radar beam will be blocked,
causing a shadow area where no object will be detected by the radar. The angle of the shadow is called the 
dead angle. To avoid the shadow, the radar antenna position should be changed to a better place to
minimize this effect. If this is not possible, the operator should be aware this dead angle exists while 
operating the radar.
