4-36

False echo by sidelobe

An ultrasonic wave is emitted only in the direction set by the 

TILT

 control, however 

there are some emissions outside the main beam. These are called sidelobes. The en-
ergy of the sidelobe is fairly weak but when the water is comparatively shallow and the 
bottom is rocky and hard, strong signals are detected by the sidelobe. These are rep-
resented on the display as a false echo as shown below. 

Noise and interference

Interference from a sonar on another ship appears on the screen as shown in (A). (B) 
shows Interference from electrical equipment on board own ship. Noise from marine 
life appears on the display as shown in (C).
