3R41 “Volna”

The 3R41 “Volna” (Cyrillic: 3Р41 «Волна», NATO designation: “Top Dome”) is an X-band missile guidance and target illumination radar for the Russian maritime missile complex S-300F (NATO designation: SA-N-6 “Grumble”).

The radar uses a semi-circular radome with a diameter of 4 meters. The antenna is a passive, radiation-fed phased-array antenna (reflection type). The primary radiator is located in the small nipple at the tip of the radome. The second much smaller radome is the transmitting antenna for the missile commands. The three cylindrical radomes at the bottom part of the platform are intended to cover the auxiliary side lobe suppression antennas.
