Ground Sensor Equipment (BSA)


Manufacturer: Rheinmetall Defense / Germany

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.
