OVERVIEW: The 9S18M1 radar (NATO name: SNOW DRIFT) is a 3-D acquisition radar operating in the centimetric Band.
DETAILS: The 9S18M1 SNOW DRIFT is a mobile 3-D radar that uses an electronically steered pencil beam. The system incorporates frequency agility, giving it enhanced resistance to ECM. The SNOW DRIFT generally receives early warning from brigade-level surveillance radars such as the SPOON REST before acquiring the target. The radar can track up to 50 targets at a time, and provide target designation on six targets. Weapon systems associated with the 9S18M1 SNOW DRIFT include the SA-11 GADFLY and the SA-17 GRIZZLY.
