Description
The Giraffe 50AT Norwegian Mobile Air Defense Radar System is a C-band (NATO G-band) (4–6 GHz) 2D air surveillance and tracking radar for air-defense operations and providing target designation to ground-based air-defense and surface-to-air missile (SAM) systems. The power generator and communications equipment are in the front unit with the driver and unit commander, and the radar and command-and-control units are in the rear unit. The Giraffe 50AT, on its Bv 208 all-terrain chassis, can swim and traverse snow or marsh.

Chassis
The system is installed on the two-unit Bv 206 all-terrain vehicle, of which 11,000 have been built mostly for military applications. The system is air-transportable in a Lockheed Martin C-130 Hercules transport aircraft.
Crew
The Giraffe 50AT requires only two operators, who sit at a console incorporating high-resolution color raster displays developed by FIAR. The graphics generators are based on three Motorola 68020 32-bit microprocessors, and the complete Giraffe 50AT system has seven CPUs – implemented as gate-array single-chip processors – with a combined power of around 10 MIPS (million instructions per second). Software is written in a real-time variant of the Pascal high-order language, and comprises 50,000–200,000 lines of source code, depending on the application.
Cargo Capacity

Moving Target Indication (MTI)
The system also has the advanced Moving Target Indication (MTI) filter with automatic wind compensation and detection of hovering helicopters. There is also a special, anti-radiation missile protection mode. The reaction time of the system is very low as the radar picture is updated every second.
Data communications consist of narrowband data channels for plot-and-track transmission.
The derived data can be sent to terminals up to 20 RBS or 70 SAM launch stations through a specially developed communications system.
MTI Improvement Factor
40 dB (est)
Power
15 kW (peak, output); 300 kW (average, output)
Note #1
Up to three NALLADS can be linked together to defend a large area. The then Ericsson Microwave Systems, in conjunction with Ericsson Radar Norge, developed the software for the system while the weapon control terminals came from Siemens (Norway).
Note #2
The Giraffe 50AT has the ability to exchange data with Giraffe 75 and AMB systems to facilitate radar co-operation and the compilation of a local air picture. The system can also be integrated with an IFF subsystem (including MK XII).

Protection
Armor
Depends on the Variant. An armored variant of the Bv 206 is the Bv 206S. It has modified cabs and armor plating on all its bodywork. A recent member of the Bv 206 family is the BvS 10 improved armored version. It is a new larger vehicle, with improved load capacity. The BvS 10 has the same superior mobility in difficult terrain, combined with the same speed on road.
