Secure and Resilient Infrastructures
SELEX Systems Integration has extenstive experience in producing
and implementing bespoke security systems for its clients. Drawing
upon expertise, processes and technologies developed in both
civilian and military safety critical systems, we provide our
customers with solutions that address a variety of security,
resilience and business continuity problems including the emerging
security requirements resulting from perceived criminal / terrorist
threats. These include:
Close Area Security Solution
SELEX Systems Integration has developed a capability that
resolves several problems in the detection of intruders within
complex environments. The concept integrates several proven
technologies to provide the detection and identification capability
of the human security guard, whilst introducing an Identification
Friend or Foe (IFF) element that resolves ambiguities associated
either with residual guard forces employed on mobile patrols, or
friendly response forces interdicting a threat.
SELEX Systems Integration’s architecture employs a millimetric
radar to make initial detections. The current 77 GHz FMCW radar is
rugged and has the necessary built-in self-test, condition
monitoring and calibration to reduce system operator input during
setting up. The radar system scans out to 800 metres once per
second with a resolution of 25cm. Intelligent assessment of threat
is provided by integral Site Security System software which detects
movements of targets in its scan range, but minimises the effect of
environmental movement such as motion of foliage. Multiple radar
systems can be networked together to provide complete coverage of
expansive sites and these can be monitored from a single control
and display position. ‘Look Zones’ can be specified on the system
where any detections outside a user-defined geographical area will
not lead to an alert, unless a target subsequently moves into a
Look Zone.
The classification and identification of the target is assisted by
a PTZ camera which automatically slews onto the radar contact. The
camera is usually installed in the same vicinity as the radar, to
mitigate against the effects of parallax masking. However, the
system can be configured for either a centralised or displaced PTZ
camera.
The SELEX Systems Integration IFF sub-system offers significant
benefit over existing radar / CCTV systems. Friendly forces, and
potentially people and items that require protection, are tagged
with a PDA-sized device which constantly transmits encrypted
identity and positional data to a base station. This positional
data is correlated with the radar track data, and those that match
IFF tag data are classified accordingly. The correlation process
not only allows the system to disregard patrolling friendly forces
and ‘tagged’ assets (thereby reducing false alarm rates) but also
makes response forces’ positions clear on the system Graphical User
Interface (GUI), facilitating vectoring to an emerging threat
should the situation arise.
As the RF-based tagging sub-system acts independently from the
radar / CCTV sub-system, the geographical range of positional data
of friendly assets is only bound by the range of the RF coverage
achieved. This enables tracking of friendly assets far beyond the
range of the radar.
In a complementary mode, stationary items can be tagged, and
alerts can be provided if they are moved. Geo-fencing provides an
alternate mode where an alert is made if a tagged asset is moved
outside a pre-defined area.
The system is supplied as standard with the ‘Hunter’ display
package, allowing graphical representation of the immediate
environment and the relative positional information of friends,
unknowns and hostiles. The display can be loaded with a variety of
underlays including 2D mapping, Google Earth data, or satellite
data. Track information from the radar and IFF systems will
interface to most current command and control systems. The GUI
underlays can also assist in tactical planning, with
intervisibility algorithms establishing blind spots and shadow
areas in advance of deployment. This environmental analysis will
provide the information required to build a more extensive security
system including the requirement for other sensors including PIR,
vibration, fibre-optic modulation, and fixed CCTV, or even lead
staff to a conclusion that, in some instances, manned guarding may
still be required to block certain avenues of approach.
The system can operate independently of fixed power supplies,
running off its own power unit, or even, for more limited periods,
a dedicated battery. The units are packed in rugged containers and
can be loaded into a single 4x4. The complete system is mobile,
self contained and can be set up in under 15 minutes for a single
radar / CCTV head, with autonomous alignment and self test
facilities requiring little or no human input.
Harvester Data Miner
This is a generic tool enabling rapid and autonomous access to
open source data bases. The technology mimics the behaviour of a
human user, thereby avoiding server denials that would be triggered
by traditional mining technologies. MDA Harvester is a version of
the Harvester family which is specifically tuned to search the
maritime information domain, by mining positional and data
intelligence for specific ship names.
Harvester Data Miner is able to reduce the searching and
collation burden from hours to a matter of seconds, enabling the
user to focus their resource on analysis, rather than data
gathering and qualification.
The mined information can be presented in any format as demanded
by the user, from simple traffic light reports to complex analysis
and visualisation.
