RAN-30X

The RAN-30X alias MM/SPS-791 (MM stands for Marina Militare, a nomenclature for the Italian Navy, similar to the US-Army/Navy's nomenclature AN/…) is a 2D shipborne multimode surveillance radar operating in X-Band. It can operate as a primary sensor for combined surface and air surveillance on board patrol vessels or as a specialized anti-seaskimmer sensor on board major Surface Combatant Vessels.

The antenna is mounted on a mechanical Roll and Pitch stabilised platform. The primary radar antenna is a parabolic reflector with two different beams: beam one forms a Cosecant Squared pattern, beam two (providing a higher gain) forms a Pencil-Beam applied for anti-missile detection and Over-the-Horizon mode. The antenna is designed to house the IFF antenna in a back-to-back configuration.
