Forward-scattering radar system for detection of small-sized and low-observable low-flying targets.
The multi-position radar system forms a radar fence of an overall extension of up to 500 km and detects any airborne objects.
CAPABILITIES
- automatic detection and measurement of coordinates and trajectory parameters of airborne targets including small-sized low-flying aircraft, cruise missiles and Stealth targets;
- target class recognition;
- radar data output to air defence operations centres for enhanced readiness of the forces and facilities.
The Barrier-E multiple-link radar system extends the radar field of an air defence complex to low and very low altitudes by building up 'radarfences'.
THE FORWARD-SCATTERING RADAR METHOD OFFERS A NUMBER OF ADVANTAGES
- target 'visibility' increases by a factor of 10*3-10*4 as compared with conventional radars;
- detection performance is not degraded by antiradar coating on the target;
- detection of targets that are not easily if at all detectable by conventional radars, such as:
Light aircraft and hang gliders; / cruise missiles;stealth aircraft;
Remotely controlled air vehicles; / low-altitude fighters;
- low radiated power;
- high detection probability for small targets;
- low false alarm rate;
