This section covers technical means intended for search, localization and technical analysis of indoor unauthorized radio emission sources. Main users of such systems are law enforcement, overseeing, security agencies.
ARC-D19R and ARC-D13R systems function inside engineering structures, buildings or in zones of the monitored object and ensure revealing of unauthorized radio emission sources, including their identification and localization. They use remote modules – devices installed inside protected premises, to which wide-band antennae are connected. In turn, portable modules are connected to control units.
In ARC-D13R system, remote modules contain analogue radio receiving tracts, signals are transmitted to the control units on a low intermediate frequency, which significantly decreases the negative influence of antenna effect in long cable lines and makes total dynamic range of the system very similar to dynamic range of analogue paths. Digital processing of signals from outputs of remote units is performed consecutively pair by pair.
Key distinction of ARC-D19R Monopulse Remote Radio Monitoring System from ARC-D13R is that its external units are full-fledged digital radio receivers that include both analogue and digital paths. Output signals from all remote units of ARC-D19R system are transferred in digital form to control server simultaneously, so they are processed simultaneously as well providing for detection of unauthorized radio emissions and localization of their sources even in case of single short radio pulse.
Transfer of signals in digital form eliminates antenna effect completely preserving dynamic range and enables use of standard network infrastructure for control and data transfer. Without additional routers, the portable module is controlled within a distance of 100 m via the twisted pair, and within much greater distances via the optic cable.
Due to use of remote units based on full-fledged digital radio receivers, simultaneous processing of signals, their high-precision time- and frequency-synchronization, and standard infrastructure ARC-D19R monopulse system has a range advantages compared to ARC-D13R, including high probability of reliable detection of short signals, higher performance, flexible scalability, extended options for identification and localization of radio emission sources of digital communication standards.
ARC-D11 Two-Channel Radio Monitoring System based on ARGAMAK-D11 Two-Channel Radio Receiver with max. simultaneous bandwidth of 24 MHz (model 4) or 100 MHz (model 5), high performance and extended functions provides for solutions of wide range of tasks related with detection of facts of unauthorized radio emissions search indoor, inside transport means and afield that cannot be solved by ARC-D19R.
ARC-D10R is applied for dealing with task of revealing wireless networks in protected object. The main hardware components of this sytem are ARC-ABS External Hardware-Software Analyzers of Wi-Fi, Bluetooth, Zigbee wireless networks. They operate under control of SMO-ARMADA Software Package providing for detection and identification of Wi-Fi access points and subscriber devices of IEEE 802.11a/b/g/n/ac standards, their localization and outputing the results in digital floor plan, as well as presenting topology of found networks.
ARC-RP3M Handheld Direction Finder is intended for manual direction finding (including selective) and localization of radio emission sources, as well as for wide variety of radio monitoring tasks afield and inside premises, transport means and within protected area.
