ISRAELI VFT
(4xPSK 75 Bd/ 1xFSK 150 Bd)
ACF
The ACF of the online encrypted FSK-system
used in this VFT-aggregate, shows a characteristic 96 bit/
192 bit spike during the phase-in procedure
only. Similar to the NATO RATT system, this system starts
with fast reversals, followed by the crypto
preamble. During traffic-condition, the system shows no apparent
ACF (Mark/ Space ratio of 1:1)!
