OVERVIEW: The TOMBSTONE [30N6]  radar is a medium range, mobile, 3D,  phased array, target illumination and guidance radar with an ABM capability operating in I/J-Band (NATO).

DETAILS:    The TOMBSTONE  radar is a derivative FLAP LID family of radars.  It can detect aircraft and cruise missile type targets at a range of up to 300 km and ballistic missiles with launching ranges of up to 1,000 km using the sector scan facility.   It can track up to 100 tracks automatically, while engaging up to 6 targets simultaneously using up to 2 missiles per target.  Data obtained is relayed to the command post for processing and assessment, and the radar can be linked into an IADS system. 

The radar is used for target detection and tracking in normal, clutter and severe ECM environments. The 30N6 phased array is more difficult to detect and track by an aircraft's warning receiver when not directly painted by the radar, and much more difficult to jam. While it may have detectable back lobes, these are likely to be hard to detect from the forward sector of the radar. As most anti-radiation missiles rely on sidelobes to home in, the choice of engagement geometry is critical in attempting to kill a Flap Lid.

It is associated with the SA-10B Grumble (S-300)  theatre defense missile systems.    Within the SA-10 system, Flap Lid is used in conjunction with the Big Bird surveillance and Clam Shell target identification/location radars.
