Radio interception and recording of radio signals
|
|
Technical analysis of the received radio signals, including:
|
|
• search, detection and recording of radio signals in the systems with automatic link establishment ALE (2G standard)
|
|
• demodulation of radio signals generated according to standard MIL-STD-188-110B
|
|
• demodulation of radio signals with frequency manipulation and speed of manipulation up to 300 Bd
|
|
• measurement of basic parameters of radio signals (frequency band, signal/noise, speed of manipulation, central frequency)
|
|
Power supply system provides:
|
|
• possibility of connection and work of radio-electronic equipment of direction finder from an external network of power supply voltage 220 V 50 Hz by means of the network extension piece on the distance of about 50 m from the connection point
|
|
• continuous work of direction finder (minimum 24 hours) using independent power supply (220 V 50 Hz) and external network
|
|
Chassis:
|
|
OPM-8/1 direction finder is based on two specialized cross country vehicles KamAZ. Hardware compartments are equipped with life-support subsystems (air-condition, power supply, filter-unit with pressurization), safe vault for papers, rack for weapon storage
