GIRAFFE Radar
The air surveillance radar Giraffe AMB (Agile Multi- Beam) is a representative of a family of stationary and mobile air defense systems, short and medium range of the Swedish company Ericsson, a pulse - Doppler air surveillance radar in the G- band with a C ³ I- combat control center (C ³ I: Command, Control, Communications and Intelligence ) combined.
Features
The Giraffe AMB is a real 3D radar, which was developed specifically for the target allocation of air defense missile systems from short and medium range and is equipped with an active phased array antenna. The name stands for AMB Agile Multi Beam and means about fast-moving jet sequence, that is, several different shaped and directed antenna patterns can be broadcast or received in rapid succession.
The antenna produces a wider transmit beam, which covers all areas of elevation angle. In the time of reception, the phased array antenna multiple narrow reception patterns for simultaneous reception of multiple elevation areas with differentiated range. So are recorded with a data update rate of about one second and extremely high -flying targets. All target coordinates are calculated with the monopulse method and create a digital target signal with great accuracy. The side lobes of the antenna are reduced to a minimum and thus provide the Giraffe AMB high Widerstandsfähigleit against active interference. While the radar in normal operation sends a pulse power of 25 kW, is sent with a maximum of 3 watts, to prevent detection by enemy radar warning systems, or at least delay the LPI mode.
The Giraffe AMB has been specially developed 23 BAMSE for the Swedish air defense system RBS and can be due to their standardized C ³ I- interfaces integrated into almost all anti-aircraft missile systems. Since 1978, more than 450 Giraffe radars were delivered and have since been in 18 countries outside Sweden use.
