Detection and localisation of small calibre gunshots – PILAR system
PILAR Mk II
System PILAR Mk II is the basic version of PILAR system for localisation or detection of small calibre gunshots from 5,45 to 20 mm (snipers). System works on the basis of acoustic detection caused by moving bullet. PILAR system represents fully passive device with easy installation and reliability.
PILAR Mk II system consists of two hardware parts:
- 2x acoustic sensor arrays equipped by relevant electronics
- Data Interface and Acquisition Modul (DIAM)
- Processing and display unit (Laptop, PDA)
- Two reels of cables for connecting the ASA onto the DIAM.
Key features
- Fully passive
- A full 360º of surveillance
- Detection capability: projectiles fired from small arms of 5,45 mm to 20 mm calibre with/without silencer by single and burst shots
- Fast response time: up to 3 s
- Sound alarm after shot detection
- Detection accuracy: azimuth: ± 2º
- Elevation: ± 5º
- Distance: depends on distance of array disposition (Acoustic Sensor Array - ASA)
- Detection distance:
- 5,45/5,56 mm more than 300 m
- 7,62 mm more than 600 m
- 12,7 mm more than 800 m
- 14,7 mm more than 1000 m
- Natural conditions: day, night, city, desert, woods, mountains
- Temperature conditions: from – 40ºC to 50ºC
PILAR V
Mobile PILAR V system represents device which allows to the crew of vehicle going through enemy or unstable territory to monitor and localise small calibre gunshots (5,56 mm – 20 mm). PILAR V system monitors acoustic area surrounding vehicle. If found the source of fire based on moving bullet, the azimuth, elevation and distance of the source of fire are evaluated. The result is shown on display PDA and provides information to the crew of vehicle in order to take necessary escaping or firing countermeasures.
Mobile PILAR system operates in two modes:
- „Aggressive shots“ focused on localisation of close fire directly to vehicle
- „All shots“ focused on all sources of firing in a large surroundings of passing vehicle incl. RPG, mortar bullets etc.
Key features
- Fully passive
- A full 360º of surveillance
- Autosignal after shot detection
- Evaluation of the fire source position: to 2 s
- Types of detected weapons:
- Detection capability: projectiles fired from small arms of 5,45 mm to 20 mm calibre with/without silencer in mode „Aggressive shots“, single shots, burst shots, subsonic shots in mode „all shots“
- Distance of the source of shots: from 0 m to 300 m (5,56 mm) do 1200 mm (20 mm)
- Natural conditions: day, night, city, desert, woods, mountains
- Service temperature: from – 40ºC to 50ºC
- Electric input:20 W
