VRB-12-141 /A(V/UHF) V/UHF Radio Monitoring

Additional information

GENERAL DESCRIPTION

VRB-12-141 /A(V/UHF) is designed for automatic and manual detection and analysis of military and non-military radio communications in the frequency range of 30MHz to 3000MHz

Different types of signals are supported like:

Fix frequency (analog and digital – narrow and wide band)
Burst
FH (frequency hopping spread spectrum)
TH/FH (frequency hopping spread spectrum/ time hopping spread spectrum)
DSSS (direct sequence spread spectrum)

Parameter estimation, demodulation and extraction of voice or bit stream are capabilities of this system. Protocol analysis software can be optionally added to the system to decode protocols. The system can be installed on stationary or tactical platforms and can be used with other EW equipment in battlefield as a part of command and control network.
