The Kasta 2E radar group (NATO reporting name "Flat Face-E") is a Russian radar group, consisting of the Kasta 2E1, Kasta 2E2 and their supporting systems. The Kasta system is designed to be the successor of the older Flat Face models, such as the P-15 and the P-19. Despite looking visually similar (similar radar reflectors) to the previous listed, Kasta has significant differences to the P-15 and P-19.
Development
[edit]The Kasta 2E was developed originally by the Soviet Union. Its primary objective is to overcome deficiencies or to satisfy the demand in low-level surveillance. Both radar types can be triggered with either equal or opposed phases. Both antenna types can optionally be mounted on a standard 50 meter pylon. This arrangement causes a displacement of the radar horizon which in turn increases the detection altitude up to 6 km at a distance of 150 km.
Systems
[edit]The Kasta 2E1 (51U6) system uses two antennas and consists of two vehicles:[3]
- one truck carries the antenna and its peripheral equipment
- another truck operates as command post vehicle and on a trailer unit, the external power supply is installed
The Kasta 2E2 (39N6E) system uses one antenna and consists of three vehicles:[4]
- one truck carries the antenna and its peripheral equipment
- another truck operates as command post vehicle
- a diesel-electric power plant is mounted another truck and two single-axle trailers carry auxiliary equipment
