PAWS EO Missile Warning System
Manufacturer Elisra Electronics Systems
Elisra's Passive (EO)
Missile Warning System (MWS) provides a key element in advanced
self protection systems for fighter aircraft, helicopters,
transports and commercial aircraft. can also track a threat
throughout the engagement.
By using infrared imagery and signal processing,
PAWS-2 detects and tracks incoming missile's hot plume as it
appears within a protective sphere surrounding the aircraft. The
system discriminates between threatening and non-threatening
missiles, by evaluating the missile's trajectories. When a threat
is detected, PAWS-2 alerts the aircrew and automatically activates countermeasures
(flares, chaff, decoys and DIRCM).
PAWS can track the threat throughout the
detecting a missile threat, the system filters the background
clutter by a applying several processing techniques, including
narrow spectral window, optimized for real-time signal processing,
and by applying an adaptive threshold. Threat assessment is
determined by a rapid target algorithm, which tracks each threat
frame-by-frame, and analyzes target maneuverability, relative
position, inertial data and angular velocity and intensity. When it detects a
threatening missile, PAWS-2 automatically alerts the pilot with a
warning signal and activates countermeasures while also providing
accurate information to Directional Infra-Red Counter-Measures (DIRCM). PAWS-2
also provides threat information
to other EW systems as part of an EW suite, as well as to avionics
subsystems. It can also operate as a stand-alone system.
developed specifically to protect fighters from SAMs and MANPADs, PAWS-2
systems are designed for fighter aircraft and has already deployed
with Israel's F-16Is. PAWS-1 systems are already deployed on IDF combat
and assault helicopters.
