OVERVIEW:  The TOP PLATE aka MR-710 Fregat-M2EM is a long range, 3-D, phased array air and surface surveillance radar, operating in the NATO E- band (IEEE: S-band).

DETAILS:  The Fregat family of ship-based radar systems designed to provide surveillance and detection of surface and airborne targets and to provide target designation data to weapon systems. It uses two back-to-back canted planar arrays optimized for two different frequency bands.  The radar is a serially fed frequency scanning phased-array type.

 The Fregat radar system can operate effectively in intense jamming and countermeasures environments.
