Sidelobe echoes (false echoes) 

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 energy 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 represented on the display as a false echo 
as shown below.

The bottom echo
detected by sidelobe
appears at a certain
tilt angle when the
sidelobe points ver-
tically. Also, poor
soundome projection
may result in a similar
false echo.

Noise and interference 

When the fishing ground is crowded with many fishing boats, the sonar is subject 
to interference from ultrasonic equipment (echo sounder or sonar) on other 
boats as well as those on own ship. 
 
For instance, interference from the sonar operated on other boats will show itself 
on the display as in (A) in the figure below. This interference can be suppressed 
by changing the TX INTERVAL on the H-SCAN SETTING menu. Noise from 
marine life shows itself on the displays as in (B) in the figure below. This type of 
noise can be suppressed with the interference rejector on the H-SCAN 
SETTING menu.   

      (A) Inteference from                   (B) Interference from
            other sonars (yours                 marine life
            or other's)
