 The Ground Sensor Equipment BSA uses an imaging
infrared sensor system to detect, classify and identify personnel,
tracked and wheeled and tracked vehicles. The passive, autonomous,
covert sensor can be placed (or buried) near roads or tracks. The
seismic geophone), magnetic and acoustic (microphone) sensors are
detached from the main units and positioned directly by the
roadside.
The central processor unit, equipped with an IR line
camera, a Passive Infra-Red (PIR) sensor and additional microphone
is positioned at a 20m distance, camouflaged or buried under the
surface. The feeds from the remote sensors are channeled to the
central processor unit, where they are processed and compared for
signature matches. When such a match is confirmed, an alert is
transmitted, with target classification data, via
burst-transmission data link (using 150ms bursts) to a display
unit at a distance up to 10 km.
A unique feature of BSA is its learning ability. When
new vehicles or other unfamiliar targets are detected, their
specific signatures are stored in the device's memory and later
retrieved to update the target library. Another advanced feature
is the automatic adaptation to environmental conditions, such as
filtering of acoustic background noise and utilizing geophone
filters to adjust operation to the specific soil properties of the
sensor's location. The sensor can also provide close-in security
for deployed positions, including self protection of the
reconnaissance patrol vehicle. Multiple sensors can be operated by
a reconnaissance vehicle, to keep a wide area under.
