Interference Rejection
This feature is used to eliminate the radar
interference wave from other radars.
When radars having the same frequency band
as your radar are used near your ship, the
interference noise from transmission signals of
other radars appears on the radar screen.
Though the appearance of the interference is not
uniform, in most cases, this interference noise
pattern is spiral or a radiation form.
This unit can reduce the interference with the
interference rejection function.

The greater the numeral is the stronger the
interference rejection.
If the interference rejection effect is too
strong, it is hard to see small targets.
So be cautious not to set it stronger.
