RAN 10S
The RAN 10S alias MM/SPS-774 was an operating in F-Band high-power combined maritime Air/Surface surveillance radar (so-called: ASu-Radar). It is suitable for installation on medium tonnage ships, such as destroyers, frigates and corvettes. The design philosophy is the same as that of the RAN-3L and a number of items are common to both systems.
The main features are high elevation coverage, elevated data rate and high precision/resolution. The use of a coded waveform in conjunction with digital processing of the received signal gives excellent capabilities of clutter and jamming rejection, enabling it to operate in full frequency agility while maintaining anti-clutter capabilities. The antenna is a wide parabolic reflector fed by a horn, and is providing a Cosecant-squared pattern by deviating from the ideal parabolic shape of the reflector curvature using a “lower lip”. It is roll and pitch stabilised and can accommodate an identification friend-or-foe antenna, mounted on top of the reflector.
