Textron Systems is developing the Tactical
Unattended Ground Sensor (T-UGS) and Urban UGS (U-UGS)
families of sensors as part of the U.S. Army's FCS program.
T-UGS is used as a rapidly deployable sensor unit, each
equipped wit multi-modal sensors to detect vehicles,
personnel and aircraft and act as an ISR network node.
The T-UGS unit also has built-in controller performing
initial signal processing target classification and
determining bearing to the target, offering false target
rejection. Additional situational awareness features
of the T-UGS include Chemical, Radiological and Nuclear
(CRN) early warning detection/marking as well as marking
cleared lanes through obstacles and hazards by employing
Hazard Clearing Lane markers (HLCM). Both CRN and HLCM
missions provide warning signals to approaching manned
and unmanned systems to ensure safe passage.
Elta also introduced a new range of unattended ground
sensors network (USGN) as part of its EL/I-6001
tactical intelligence and recce collection capability.
This modular network of autonomous, distributed sensors
includes seismic, acoustic and electro-optical sensors
and miniature ground surveillance radars. Each sensor
comprises a sensitive microphone for acoustic detection,
a geophone to pick-up seismic vibration from nearby
movement, a GPS receiver, communications transceiver
and low-power controller and signal processor. The sensor
can pick up moving heavy vehicles (such as tanks) from
a distance of 500 meters and walking humans from 50
meters. These sensors can operate autonomously or in
combination, optimizing area coverage, and facilitating
target detection, classification. To save power, the
EO sensors are maintained 'dormant', activated only
when other sensors UGS confirm a target is in sight.
Specializing in the seismic domain, Spydertech, an
Israeli company specializing in security applications
of seismic monitoring systems unveiled at Eurosatory
a 3D seismic surveillance system capable of accurately
detecting and tracking movement underground and on the
surface. The new system based on proprietary sensors
and hardware developed specifically for underground
applications. The system comprised of up to 250 sensors,
each performing signal processing at the sensor, contributing
to high probability of target detection with low rate
of false alarms.
In addition, the system can detect subterranean activity
at depths of 35 meters. Another type of virtual fens
is developed by Magna
BSP. These systems are already being deployed operationally
as part of perimeter security systems with further work
and customer evaluations done with tactical, deployable
systems, supporting ad-hoc protection of forward operating
bases and deployed forces. Utilizing both FLIR and CCD
sensors, enabling automatic switching between sensors
when visibility conditions are reduced/ The sensors
are staring at the same time and position at the same
field of view thus contributing to the system's low
false alarm rate. These systems demonstrated less than
one False Alarm Rate over 24 hours (FAR/24) while detecting
100% of targets at the zone of interest.
Controp have shown the Spider thermal area scanner
at Eurosatory, a system currently being employed for
border protection by the Israel Defense Forces. The
system's sensors and command and control console were
on display, showing the system's capability to cover
wide area of interest, track suspicious targets and
provide target data Spider and relevant close-up images
in real-time.
