76N6 Low Altitude Acquisition Radar

NATO-Designator “Clam Shell”

Currently being marketed by the Moscow-based LEMZ (Lianozovo) company, the 76N6 is a low-altitude FMCW search and acquisition radar designed to detect and track approaching and receding low radar cross section targets, particularly cruise missiles. The system will detect targets at extremely low altitudes in ground clutter under intense ECM conditions. This system is described as fully automatic and provides target track information for the fire control system of the static SA-10A or mobile SA-10B Grumble area defence SAM. Approaching and receding target velocity, range and bearing are provided, with selectable 1 or 6 degree vertical beamwidths, and selectable beam polarisation. It uses a split antenna arrangement with a large beak to prevent spillover from the transmitter. The doubly curved transmit and receive reflectors each measure 9.2 ft per side.
