PIRI (Panoramic Infrared Imaging) – IRST Infrared Search and Track System

​PIRI is a high performance Infrared Search and Track system designed for maritime platforms in order to passively detect and track multiple air and surface vehicles and missiles with its staring sensors. PIRI is able to observe the perimeter of the maritime vehicle simultaneously in dual-band IR. The large elevation FOV makes the system capable of observe air to surface threats effectively. Display of both MWIR and LWIR spectrum in 360° azimuth as a panoramic image makes PIRI, a comprehensive solution for ships. Distributed Sensor Architecture makes the system modular for any platform.

Applic​​​​ations

Main Feat​​ures

ADVERTISEMENT

• Passive Search and Track
• Detection and tracking of air and surface vehicles and missiles
• Simultaneous Detection and Tracking of Multiple Targets
• Staring Sensors
• Very high image update rate compared to rotating systems
• High image update rate means shorter time for track declaration, better track declaration range performance and longer available time for counter measure disposal
• Very low false alarm rate

• Simultaneous Dual-Band IR Imaging
•  Simultaneous MWIR and LWIR imaging which results in low false alarm rate
• Large Elevation FOV
•  Simultaneous detection of sea-skimming missiles and higher-altitude airborne targets
• Display of both MWIR and LWIR full azimuth 360° panoramic image
• Distributed Sensor Architecture
• Full azimuth coverage of 360° by placing sensor units around ship mast
•  No blocked view, in contrast to rotating systems
• Movement in Elevation
•  Ability of detecting and tracking of higher-altitude threats
• Accurate Stabilization
