TheSNR-75 (also referred to by theNATO reporting nameFan Song) is a series of trailer-mountedE band/F band andG bandfire control and tracking radars for use with the SovietSA-2 Guidelinesurface-to-air missile system.
The Fan Song radars are capable of tracking 6 targets at a time, and can guide up to three missiles at once to it. The radars feature two orthogonal antennas, one for azimuth and one for elevation, which can operate in atrack-while-scan mode. These antennas transmit 10 × 2 degree or 7.5 x 1.5 degree beams and perform a 'flapping' motion as they scan their sectors.[1][2]
The Fan Song E includes two additional parabolic dishes for narrow beam andLORO tracking modes.[3]
