The Fan Song is the NATO reporting name for SNR-75 series of trailer-mounted E band/F band and G band fire control and tracking radars for use with the Soviet SA-2 Guideline surface-to-air missile system.
Description
The Fan Song radars are capable of tracking a single target at one 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 a track-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.
The Fan Song E includes two additional parabolic dishes for narrow beam and LORO tracking modes.
