Note: Control to be used conscientiously since greater reduction in interference may also
mean eliminating weak but important echoes.
4. Target BOOST
– This function is used to enlarge the target images on the screen. It has 3
enlargement methods:
• Boost 1
• Boost 2
•

ff.
5. Scale
– We can adjust the scale of the image in terms of metres (characteristic of the BR24
system) taking the minimum scale (or most distant point we can see) from a minimum of 50
metres to 48 miles since above this, the quality of information will be lost.
6. Target expansion
– Mode used for angled image expansion.
7. Transmission
– An area inside the window that gives us immediate information about the
type of transmission being used and therefore viewed (in our speci
fic case, TXRX 5 – FMCW).
Limits
The ARGUS FMCW system has some limits, for example:
When the two antennas, which we remind you, transmit one in continuous mode (FMCW)
and the other in pulse mode, are facing the same direction on the primary PPI screen, rods
will be shown, laid out like the rays of the sun. This problem is caused b
y the different trans-
mitting methods and can be reduced using the Interference Rejection set to HIGH in the
primary PPI control. The FMCW system cannot be viewed on the primary PPI, but only on the
additional PPI and therefore, it cannot be combined with the other transmission modes (see
“TXRX interswitch menu (C
onfiguration video combination)” on page 79).
