 (SHORAD) missile or gun systems or for use as gap-fillers in a larger air defense system. The radar gets its name from the distinctive folding mast which when deployed allows the radar to see over nearby terrain features such as trees, extending its effective range against low-level air targets. The first systems were produced in 1977. By 2007, some 450 units of all types are reported as having been delivered.

Description

Giraffe is a family of G/H (formerly C-band) frequency agile, low to medium altitude pulse doppler air search radars and combat control centers which can be used in mobile or static short to medium range air defense applications. Giraffe is designed to detect low-altitude, low cross-section aircraft targets in conditions of severe clutter and electronic countermeasures. When equipped as an air-defense command center Giraffe provides an air picture to each firing battery using manpack radio communication.

GIRAFFE uses Agile Multi-Beam (AMB), which includes an integrated Command, control and communication (C3) system. This enables GIRAFFE to act as the command and control center in an air defense system, it can also be integrated into a sensor net for greater coverage. It is normally housed in a single 6m long shelter mounted on an all-terrain vehicle for high mobility. Additionally the shelter can be augmented with Nuclear, Biological and Chemical

Variants

Giraffe 40
This is a short-range (40 kilometres (24.9 mi) instrumented) air defense radar with command and control capability. It employs a folding antenna mast that extends to a height of 13 metres (42.7 ft) when deployed and can be integrated with an Interogation Friend or Foe (IFF) capability. Coverage is stated to be from ground level to 10000 metres (32,808.4 ft) in altitude. In Swedish service the radar is designated PS-70 and PS-701 and provides target data to RBS-70 SHORADS missiles and 40mm Bofors guns. A more powerful version with a 60 kW transmitter is known commercially as Super Giraffe and in Swedish service as PS-707. These radars are no longer marketed.

Giraffe 50AT
This is the model used in the Norwegian NALLADS air defense system which combines the radar and RBS-70 missiles with 20 mm

 anti-aircraft guns to provide low-level air defense for the combat brigades of the Norwegian army. Mounted on a BV-202 all-terrain tracked vehicle this version has an instrumented range of 50 km (31.1 mi). The antenna extends to a height of 7 metres (23 ft) and the system can control up to 20 firing units of guns or missiles or a combination of both. The Command and Control system features fully automatic track initiation, target tracking, target identification (IFF), target classification and designation, hovering helicopter detection threat evaluation and handling of "pop-up" targets. It can also exchange data with Giraffe 75 or AMB systems as part of a larger network.

Giraffe 75
This features a 13 metres (42.7 ft) antenna mast and is normally carried on a 6x6 5-ton cross-country truck which carries the radar and command and control shelter. Instrumented range is 75 km (46.6 mi) and altitude coverage extends from ground-level to 10000 metres (32,808.4 ft). An optional add-on unit extends the radars coastal defense capabilities. In Swedish service the radar is designated PS-90. In the Greek Air Force Giraffe 75 is used in combination with Contraves (now Rheinmetall defense) Skyguard/Sparrow fire control systems. 1 Giraffe typically controls 2 Skyguard systems each with 2 twin 35 mm GDF-005 guns

Giraffe S
Optimized as a mobile radar for un-manned remote-controlled applications as a "gap-filler" in air defense early warning systems concentrating on small, low-flying targets over a long distance. It can also be employed as a coastal surveillance radar where targets are small surface vessels and sea-skimming missiles or aircraft
Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet. An aircraft counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines.Although...

. A new antenna extends range coverage to 180 km (111.8 mi) with altitude coverage from ground level to 6000 metres (19,685 ft). The antenna mast extends to 8 metres (26.2 ft).

GIRAFFE AMB
This newest member of the family, providing multi-beam 3-Dimensional air coverage at 5.4 to 5.9 GHz with instrumented ranges of 30 km (18.6 mi), 60 km (37.3 mi) and 100 km (62.1 mi), the altitude coverage is extended from ground-level to 20000 metres (65,616.8 ft) with 70-degree elevation coverage. Data rate is 1-scan per-second. Its maintained pulse density suppresses high cluttering in adverse weather conditions. Ultra-low antenna side-lobes combined with pulse-to-pulse and burst-to-burst frequency agility provides some resistance to jamming. As in previous Giraffe radars automatic hovering helicopter detection is provided as is an artillery and mortar locating function, allowing the radar to detect incoming rounds and give 20 seconds or more of warning before impact. Giraffe AMB is the principal sensor of the Swedish RBS 23

Sea GIRAFFE
Sea GIRAFFE is the naval variant of the GIRAFFE radar with AMB technology. It can detect air and surface targets from the horizon up to a height of 20000 metres (65,616.8 ft) at elevations up to 70º, and can simultaneously handle multiple threats approaching from different directions and altitudes, including diving anti-ship missiles. Also, it is specialized for rapidly detecting small, fast moving targets at all altitudes and small surface targets in severe clutter. Its roles include :
  • Air surveillance and tracking
  • Surface surveillance and tracking
  • Target identification for weapon systems
  • High-resolution splash spotting
