Scrum Half - target engagement/missile tracking radar

The phased-array target engagement/missile tracking radar used by the Tor-M1 carries the NATO reporting name “Scrum Half” (i.e. Tor-M1’s target acquisition, and target engagement/missile tracking radars bear collective NATO designation). A rugby scrum-half is the vital link between forwards and backs but does much more. The General on the pitch, a scrum half is the boss of the Forwards and is clear and confident in demands for the type and speed of ball wanted to pass on to the Backs.

The 3D pulse Doppler electronically beam steered E/F-band surveillance radar provides range, azimuth, elevation and automatic threat evaluation data on up to 48 targets for the digital fire control computer processing system. Automatic track initiation can be performed on the 10 most dangerous targets, which are categorized and prioritized in order of threat for engagement. The operator reconfirms the highest priority target choice and tracks this target before firing the missile. The maximum radar range is stated as 25 kilometers, but the rapid five to eight second reaction time [including fire control target prioritization] suggests a somewhat greater range. The radar antenna, on top of the turret, is swung through 90º to the horizontal position for travel. Target radar surveillance is carried out on the move but the vehicle would normally come to a halt for missile launch.

The phased-array pulse Doppler G/H-band tracking radar is located at the front of the turret. This electronically steered radar is capable of simultaneously tracking two targets traveling at speeds of up to 700 km/h in all weather conditions, and countering threat ECM operations. The antenna assembly can be folded down for travel.

Mounted on the top left of this radar is a small vertical pointing antenna which serves to initially acquire the missile after launch before it is handed over to the main tracking/guidance system. On the lower right side of the tracking radar is an automatic TV tracking system with a range of 20000 m that complements the tracking radar and enables the system to operate in a heavy ECM environment.

Scrum Half is a Pulse-Doppler electronically steered radar with an average power output of 0.6 kW, providing a maximum tracking range of 20 km. The target engagement radar, located at the front of the TLAR’s turret, is capable of determining 4 coordinates of the selected target. The coherent-pulse radar station of the all- round view solves the problem of detecting air targets and gives out their coordinates. The station is equipped with a friend-or-foe identification system. It works in the centimeter wave range with frequency control by the elevation angle of the beam. Simultaneously, a survey of the elevation angle at once by three rays can be carried out, the order is established using a computer. Each beam has a width of 4 ° in elevation and 1.5 ° in azimuth. One beam is able to overlap a sector at 32 ° in elevation. In the main mode, the scanning speed of the detection zone is three seconds, while the lower part of the zone is scanned twice. Additionally, there is a three-beam viewing mode with a pace of 1 second. Marks with the coordinates of the detected targets are tied to the tracks. In total, the target detection station can tie 10 tracks on 24 detected targets.

Targets with velocity vectors, track numbers, degree of danger and the number of the beam in which the target is located are displayed on the indicator of the combat vehicle commander. In the presence of strong passive interference, it is possible to blank the problem area of ??the survey and enter the target coordinates in the computer using manual marker overlay and manual coordinate acquisition. The maximum errors in determining the coordinates do not exceed half the resolution of the target detection station. Resolution: no worse than 1.5–2 ° in azimuth, 4 ° in elevation and 200 meters in range. F-15 Type Aircraft Detection Probabilityat an altitude of 30 to 6,000 meters and a range of 25–27 km is 80%. Unmanned aerial vehicles are detected at a range of 9 to 15 km with a probability of 70%. Helicopters located on the ground, with propellers turned on at a distance of 6–7 km, can be detected with a probability of 40–70%, hovering in the air at a distance of 13–20 km — 60–80%, when jumping to a height of 20 m at a distance of 12 km - not less than 60%.
