96L6E “Cheese Board”

96L6E “Cheese Board” is a 3D early-warning and acquisition radar operating in C-band designed to replace the 36D6 “Tin Shield B” and 76N6 “Clam Shell”. It is used in conjunction with the SA-10 “Grumble” (S-300) and SA-21 “Growler” (S-400) theatre defence missile systems. Three operators are needed to run the set. Up to five operator consoles are provided.

The phased array antenna with 96 radiating rows employs mechanical beamsteering in azimuth and electronic beamsteering in elevation. The radar is a frequency hopping design intended to provide high jam resistance and high clutter rejection. There are two operation modes implemented: Low altitude targets can be acquired by constraining the mainlobe elevation angle between -3° and +1.5° using an antenna rotation of 5 rpm. This slow rotation allows a better clutter rejection with a subclutter visibility up to 70 dB. All altitude targets can be acquired by constraining the mainlobe elevation angle between -1.5° and +20° using an antenna rotation of 10 rpm. As a third mode the radar can operate in a sector search.

The 96L6E measures range, azimuth and elevation and performs up to 100 local tracks automatically. It classifies four different target types: aircrafts, helicopters, UAVs, and missiles.

After relocation the 96L6E can be set up by three operators in less than 5 minutes.
