OVERVIEW:  The Cyrano I bis aka DRAC-36 radar is an  airborne  medium-range, fire-control  radar operating in the NATO  "I"  (IEEE X ) band.

DETAILS: 

The Cyrano I  radar is a  monopulse radar that uses a Cassegrain antenna.  It can detect, track and operate as a fire control radar for both the 30 mm cannon and the Matra R511 and R530 missiles and was designed primarily to engage relatively unmanuverable bombers at high altitude.   Like other second-generation air-to-air radars, it lacked a "look down/shoot down" capability.


Specifications:

	Frequency:	8-10 GHz (I-band (NATO))
	PRF:		?? Khz (air-to-air) 
	Pulse width:	?? µ sec (air-to-air)
	Power: 		300 kW (peak) 
	Scan Limits:	±60 ° azimuth, ±60 ° (air-to-air) elevation 
	Range:		20 nm (air-to-air)(estimate)
				

NOTES:  IOC: 1958.  Used in the Saab J35 Draken and Mirage III Cs.  Generally considered to be an unreliable radar.
