Dual Radar (A/B-types only)

When installing two FAR-2xx8 series radars, the image from both radars (main radar
and external radar) may be shown together on one radar display. This allows you to
take advantage of the best characteristics each type of radar has to offer. The dual
radar function is available only for A/B-types.
The following should be done from the [DUAL RADAR SETTINGS] menu, located in
the [RADAR INSTALLATION]
to enable the dual radar display:
• Set the number of the radar to use for external input at [6 EXT RADAR].
• Set [2 DUAL RADAR] to [COMBINE]. This enables the dual radar function.
• Set the sector and range to combine radar images at [4 COMBINE SECTOR] and
[5 COMBINE RANGE] respectively.
• Set the radar image you want to show in the sector at [3 COMBINE MODE]. The
manner in which the radar images appear on-screen depends on the combination
mode selected.
TT information
When a TT target crosses over the boundary line of the display area, its information is
passed to the other radar display. Tracking of the TT continues. The TT number
changes depending on the number of the antenna which acquires the TT target.
The lowest numbered Processor Unit assigns TT numbers "001" to "100", the other
Processor Unit assigns "101" to "200".
Note: Only manually acquired target data is transferred.
