9S18M1 Snow Drift Russian Mobile 3D Coherent-Pulse Target Acquisition Radar

The 9S18M1 radar (NATO name: SNOW DRIFT) is a 3-D acquisition radar operating in the centimetric Band. The 9S18M1 SNOW DRIFT is a mobile 3-D radar that uses an electronically steered pencil beam. The system incorporates frequency agility, giving it enhanced resistance to ECM. The SNOW DRIFT generally receives early warning from brigade-level surveillance radars such as the SPOON REST before acquiring the target. The radar can track up to 50 targets at a time, and provide target designation on six targets. Weapon systems associated with the 9S18M1 SNOW DRIFT include the SA-11 GADFLY and the SA-17 GRIZZLY. --- Additional Data (TRADOC ODIN WEG) --- Frequency: 8–12 GHz (X, NATO Band J) Antenna Dimensions: 3.6 x 1.8 m Associated Weapon Systems: Бук-М1 (Buk-M1): 9М38 / 9M38 Role: 3D Target Acquisition Remarks: Main Buk-M1 search radar --- From Radartutorial.eu (https://www.radartutorial.eu/19.kartei/02.surv/karte093.en.html) --- The 9S18M “Kupol-M” (Cyrillic: «Купол-М»; NATO designation: “Snow Drift”) is a mobile 3-D acquisition radar operating frequency agile in the S band (IEEE designation) or in the F band (NATO designation). The radar uses a rectangular phased array antenna with mechanical rotation in azimuth and an electronically steered pencil beam in elevation. The transmitters’ waveform is alternate an unmodulated pulse and a pulse with linear intra-pulse frequency modulation (chirp). The radar can track up to 50 targets at a time, and provide target designation on six targets. It is used for target assignment for the 9K37 “Buk” air defense missile system (Cyrillic: «Бук М1»; NATO designation: SA-11 “Gadfly”). The radar was developed in 1977 and has been in the armament of some states of the former Soviet Union and Finland since 1980.
