Echo Averaging
To identify true target echoes from the sea clutter, echoes are averaged over succes-
sive picture frames. If an echo is solid and stable, the echo is shown in its normal in-
tensity. The brilliance of sea clutter is reduced to easily identify true targets from the
sea clutter.
Note 1:
Do not use the echo average function under heavy pitching and rolling to pre-
vent loss of targets.
Note 2:
This feature requires a heading signal and position data. When either signal
becomes lost, echo average is deactivated.
To correctly use the echo average function, first reduce the sea clutter properly. Leave
a little sea clutter on the screen so as not to erase weak targets. Then, do as follows:
Click the [EAV] (echo average) icon to switch the setting among [EAV OFF], [EAV 1],
[EAV 2], [EAV 3].

Target Trails
The trails of the radar targets can be shown simulated in afterglow to check target
movement. The target trails are selected for either relative or true. True trails require
a heading signal and position data.
