ARTHUR (artillery reconnaissance radar)
The ARTHUR ( ART illery HU nting R adar) is an artillery reconnaissance radar .
The artillery reconnaissance and shooting radar ARTHUR was developed by the Swedish company Saab Microwave Systems between 1983 and 1986. The first prototype appeared in 1987. After ongoing tests and further developments, the first shooting tests were carried out in 1995. The first systems were delivered in 1999. Since the start of production, the system has been continuously improved. There are now four different types of ARTHUR.
features
It is a broadband coherent radar with a traveling wave tube as a transmission power amplifier and partly uses the same technology and components as the " Giraffe AMB " radar.
The narrow diagram of the passive phased array antenna enables a high degree of accuracy in determining the location of the firing gun as soon as you grasp and briefly accompany a missile in flight. The antenna diagram is electronically panned in elevation and azimuth in a sector of 90 °. ARTHUR can process up to 100 projectiles per minute at the same time.
In addition to the reconnaissance of enemy fire units, ARTHUR can also simultaneously report the effects of its own weapons. To this end, ARTHUR searches a section of the site just above the horizon for storeys. As soon as a projectile has been detected, it is accompanied for a short time and the trajectory is ballistically calculated. The position of the projectile impact is determined from this data and, with the help of the knowledge of the exact position of the firing guns, used for direct fire correction of the own artillery.
The entire ARTHUR system can be transported by air both with C-130 Hercules transport aircraft and as an external load from helicopters.
