OVERVIEW: The P-15 radar (NATO name: FLAT FACE A) is an mobile, 2-D early warning radar operating in the "C" Band.

DETAILS:    The FLAT FACE A is a mobile version early warning radar. The P-15 can shift to one of four pre-set frequencies to avoid active interference.  Weapon systems associated with the P-15 include the SA-2 GUIDELINE, SA-3 GOA and the SA-60 57mm AAA gun.  

Specifications:

Frequency: 		810-850/880-905 Mhz (C-Band)
Power output: 		900 kW (peak)(some sources report 370-390 kW peak)
PRF:			200-800; 600-880 pps(some sources report 500-680pps)
Range Resolution:	90 m (some sources report 300 m)/ 5 degrees azimuth					
Run up time:		up to 3.3 minutes
Set up time: 		10 minutes

Detection Ranges (Fighter size aircraft)	
  	300 m altitude:	70 km 
	3000 m altitude: 140 km
 	10000 m alt.:	210-250 km

 
NOTES: IOC 1955. The FLAT FACE is frequently associated with the PRV-11 SIDE NET E-band height-finding radar. A variation of the P-15, the P-15M SQUAT EYE radar, has the antenna mounted on a 20-30 m mast for improved low altitude coverage. Because of their low power-aperture ratings this family of radars is not regarded as being very effective against low-observable aircraft and drones.
