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. From now on, all project downloads and modifications are completely free and openly available to everyone. If you were previously a member under the old system, there is no need to worry. I invite each and every one of you to explore and download everything entirely for free!
