AR-320 is operating in E/F-Band long range surveillance radar. The AR-320 radar was designed specifically as a Class 1 radar for NADGE network on NATO's southern flank but was unsuccessful.
The AR-320 is the result of collaboration between Siemens-Plessey Radar and ITT-Gilfillan. The radar is a combination of the ITT-Gilfillan series 320/3-D antenna and transmitter with the Plessey AR-3D (Type 94 radar) receiver, signal processor, raster scan displays and radar software. The ITT-Gilfillan 320 series includes such systems as AN/SPS-48 and AN/TPS-32, both of which are in service with the US armed forces and a number of foreign countries.
The UK Ministry of Defense ordered six AR-320 radarsystems in 1983.
