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.
Applications
Search and Track
Surveillance
Situational Awareness
Main Features
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
