TSCM Software RFeye® Guard software has been developed to support the specific requirements of continuous automated 24/7 TSCM monitoring. The software contains a suite of advanced tools for the identification, measurement and analysis of anomalous signals, and geolocation of their emitter sources. It also provides a configurable user interface for setup, automation and control of the RFeye Guard sensor network on a single floor, multiple floors or across multiple buildings. Advanced mapping and geolocation The location of all RFeye Guard sensors in the network together with their unit information is displayed in RFeye Guard software using maps and topographical data including SRTM. The geolocation results, including POA probability heat maps. can be overlaid on the map interface to enable target localization (see picture above). Power on Arrival is an amplitude comparison radiolocation technique that is effective over the short distances involved with in-building monitoring, due to the initial rapid drop-off in received signal power with distance from the target transmitters. It is well suited to the multitude of potential signal types that are sources of interference or indicators of covert activity, as the principle is independent of signal bandwidth or modulation type. The proprietary SyncLinc™ system from CRFS avoids the need for (or vulnerability from) re-radiating GPS indoors for synchronization between RFeye Guard sensors, and instead offers a dedicated, purpose-designed and robust synchronization technique that enables highly effective localization of detected transmitters. Sweeps and time captures The RFeye Guard software provides a familiar and simple spectrum analyzer trace for each connected RFeye Guard sensor, with real-time frequency and time domain spectra with constellation diagrams and 2D or 3D waterfall displays. A trace from each sensor in the RFeye Guard network can be output to individual displays, or displays can be combined and overlaid for more powerful analysis options with selectable data processing modules. Individual elements of a more complex mission can be controlled and configured per-sensor, for example after obtaining a POA geolocation result using a synchronized RFeye Guard network, an individual sensor can be selected based on proximity to the signal for targeted time captures and further detailed analysis. Masks triggers and alarms RFeye Guard software can be configured to issue alarms via the local system, to log files, SMS and email from user defined triggers and spectrum masks. Simple mask break scenarios can be useful for triggering alarms when any signal exceeds an expected background spectrum of known signals, or more advanced modules allow notifications on events such as detection of certain modulation types and channel identification. Automation and configuration Depending on the level of expertise of the user, the GUI can be provided as fully configurable by the user or preconfigured with simple controls. RFeye Guard software also comes with a user-friendly configuration tool to allow users to create their own custom configurations. With different access levels, it is designed to be easy to use and intuitive for operation by non-specialists whilst allowing full flexibility for set-up and programming by expert users. Each individual RFeye sensor can be assigned tasks from a large configurable menu, allowing the user to control all aspects of the system. This includes setting automated spectrum sweeps, creating RF background masks and trigger conditions, alerts from mask breakages, performing advanced signal classification and geolocating suspicious or unauthorized transmitters. RFeye Guard sensors are organized into network groups within the RFeye Guard software, enabling missions to be assigned according to building and room groups, or to single-out individual zones for focused missions. Nodes can be shared across network groups for useful differential measurements, for example comparing signals received from in-building Nodes to external or perimeter Nodes. Mission configurations can be quickly dragged and dropped between different network groups for instant switching and sharing of the monitoring tasks in different building areas. The interface for status monitoring and network control simplifies the management of extended RFeye Guard in-building networks.
