Our innovative and highly cost-effective Modular Communications Surveillance Sensor used to detect, monitor, exploit and geo-locate MF to UHF radio emissions.
Example applications for the SPECTRA Sensor systems include:
The SPECTRA Sensor system employs an I.P. Network-based architecture; each SPECTRA Sensor can be deployed standalone or as part of a multi-node local or wide-area network.
Multiple, separately located SPECTRA Sensors can be remotely operated from a single Operations Centre using wide-area communications bearers. Special measures are implemented by our Engineering Team to reduce communications bandwidth requirements where necessary.
SPECTRA is fully scalable and can be easily configured to suit specific operational requirements, from small-scale mobile platforms with few Operators to large-scale, fixed stations with many Operators.
Tailored to the Customer’s specific needs, SPECTRA can employ a combination of CommsAudit RF digital receivers and compatible 3rd-party receivers. This permits existing receiver systems such as Government Furnished Equipment (GFE) to be fully integrated into the SPECTRA Sensor system as required.
SPECTRA uses Wideband and Narrowband processing techniques to prosecute the RF spectrum.
SPECTRA includes a suite of Wideband (IF/I&Q) and Narrowband (AF/I&Q) recording and buffering sub-systems.
The buffers allow the Operator to shuttle his Wideband spectrum to correctly re-tune or apply alternate demodulation schemes to any signal captured in the Wideband recording, even if the ‘live’ transmission has ceased. The Operator is able to define his operational buffer size ‘from seconds to hours’.
Incorporating the VITA-49 Radio Transport standard for Electronic Surveillance Sensor architectures, the Wideband recorders employ multi-Terabyte storage arrays, delivering the capability to make Wideband recordings over many hours or days for manual or automatic ‘after-event’ analysis, processing and archiving. Multiple, real-time VITA-49 outputs are also available for use as streamed input to 3rd-party parallel processing systems.
A comprehensive Audio Editor suite allows the Operator to playback, cleanup and process automatically or manually invoked audio recordings for offline review, analysis and transcription as applicable.
The SPECTRA Sensor’s MF to UHF+ Direction Finding capabilities incorporate Super-Resolution Direction Finding (SRDF) techniques to produce high-accuracy Azimuth and Elevation results, even in multiple-signal environments.
SPECTRA can be configured for HF SRDF and/or V-UHF+ SRDF; the modular system architecture permits rapid reconfiguration.
Our SPECTRA digital beam-forming capabilities enable 'blind-signal separation' techniques to ensure that weaker Signals-of-Interest can be successfully prosecuted in the presence of stronger interfering emissions.
Further details concerning our SRDF and digital beam-forming capabilities are available upon request.
Based on ‘Server-Client’ architecture, each SPECTRA Client Workstation runs the SPECTRAVIEW User Interface to deliver the means of efficient sensor tasking, management and control to the SPECTRA Sensor Operators & Supervisors.
Designed by a collaborative Team of CommsAudit Software Engineers and Electronic Surveillance Operations Specialists, SPECTRAVIEW can be reconfigured in real-time to suit changing operational profiles, whether tactical or strategic.
Key features SPECTRAVIEW include:
The SPECTRA Sensor Operators’ Workstations are commercially available or ruggedised Personal Computers. The Workstations can operate in either Windows(R) or Linux Operating System environments. To ensure efficiency and maintain compatibility with any appropriate security accreditation requirements, the SPECTRA Sensor Server runs the Linux Operating System.
