3.4 

GENERAL RADAR OPERATION 

 

 

3.4.1  Interference Rejection (IR) 
 

Interference by other radars is rejected. 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 

 Procedures 

 

1  Put the cursor on interference rejection (IR) mode switching    IR   

( 

②

  lower left of the display on page 2-18) and press the [ENT] key. 

 
The interference rejection modes are switched. 
 

 IR Off  

⇒

  IR Low  

⇒

  IR Middle  

⇒

  IR High  

⇒

  IR Off  

 

 
Rejection levels of the interference rejection 

 IR Off  

: Interference rejection off 

  IR Low   

: Interference rejection level - low 

  IR Middle   

: Interference rejection level - middle 

  IR High   

: Interference rejection level - high 

 
When a high interference rejection level is selected, the radar’s ability of detecting 
small targets such as buoys and small boats lowers. 
In general,    IR Low    should be selected. 
 
 
 

 

z

 

When viewing a radar beacon or SART signal, select 
IR Off (Interference Rejection Off) because IR 
processing suppresses the video.
