9S19 High Screen (9S19M Imbir) Russian Long-Range Sector Surveillance Radar System

The specialized 9S19 Imbir is a high-power-aperture, coherent, X-band phased array designed for the rapid acquisition and initial tracking of inbound ballistic missiles within a 90-degree sector. To that effect it uses a large passive phase technology transmissive array, using a conceptually similar space feed technique to the MPQ-53 and 30N6 series radars, producing a narrow 0.5º pencil beam main lobe. The primary search waveform is chirped to provide a very high pulse compression ratio intended to provide a very high range resolution of small targets. The design uses a 16 kiloWatt ave Travelling Wave Tube (TWT) source, very low sidelobes, and frequency hopping techniques to provide good resistance to jamming. Three primary operating modes are used. In the first the 9S19 scans a 90º sector in azimuth, between 26º and 75º in elevation, to detect inbound Pershing class IRBMs within a 40 to 95 nautical mile range box, feeding position and kinematic data for up to 16 targets to the 9S457 command post. In this mode, the transmissive array is tilted back to 35º. The second mode is intended to detect and track supersonic missiles such as the AGM-69 SRAM, and sweeps a narrower 60º sector in azimuth, between 9º and 50º in elevation, within a range box between 10 and 90 nautical miles, generating target position and velocity updates at 2-second intervals. The third mode is intended to acquire aircraft in severe jamming environments, with similar angular and range parameters to the second mode. In this mode, the transmissive array is tilted back to 15º. --- Additional Data (TRADOC ODIN WEG) --- Frequency: 8–12 GHz (X, NATO Band J) Antenna Dimensions: 5 x 2.5 m Associated Weapon Systems: С-300В (S-300V): 9М83 / 9M83, 9М82 / 9M82 Role: Sector Surveillance/BM Tracking Remarks: S-300V sector/BM radar --- From Radartutorial.eu (https://www.radartutorial.eu/19.kartei/06.missile/karte016.en.html) --- 9S19M Imbir (Cyrillic: 9С19 «Имбирь», NATO-designator: High Screen) is operating in the X band mobile air surveillance and acquisition radar for S-300V/SA-12 Anti-Ballistic Missile (ABM) systems. The transmitter uses a high power Traveling Wave Tube (TWT). The transmission type of space feeded phased array antenna scans a sector of 90 degrees in azimuth, and 30 to 73 degrees in elevation.
