OVERVIEW: The  AR-325 Commander is a transportable, long range, 3-D air defense radar operating in the E/F Band.

DETAILS:  The AR-325 uses a planar-array antenna with frequency steered pencil beam groups to electronically scan in elevation. The system is highly automated. ECCM  
capabilities include frequency agility, jammer frequency analysis, jam-strobe reports and silent sector operations, ultra low sidelobes and Constant False Alarm Rate (CFAR). Remote monitoring is possible. 

Specifications:

Frequency: 		 2.7-3.1 GHz (E/F Band (NATO), S Band (IEEE))
Power output: 		 7.5 kW(average);  134 kW (peak) 
PRF:			  variable	
Range Accuracy:		 18 m (range),   0.16 degrees azimuth (est)					
On/Off time:		 unknown
Deploy/Stow Time	 240 minutes/  minutes
 
Detection Range (1m2 target):	470 km  


  
NOTES: IOC 1989.  The system is aircraft, truck and helo transportable. The AR-325 is based on the Plessey AR-3D and AR-320, but has less ECCM capability, as it was designed for export to the non-NATO market. It features increased mobility over the AR-320, by reducing the radar size and the number of shelters from three to one.
