SURVEILLANCE RADAR
The Gamma-DE radar station is intended for use in automatic and non-automatic control systems of Air Force and Air Defence Forces. It can be also used as a tracking radar for air traffic control.
The decemeter-wave band radar ensures detection and tracking of many modern air targets, including low-signature air missiles flying at high altitudes, in heavy clutter and jamming environment.
- phased array antenna with rotary assembly;
- processing, control, indicating and transmitting equipment;
- ground IFF interrogator;
- electric power unit;
- SPTA kit and test-measurement equipment.
The Gamma-DE is the advanced radar for air target detection. The radar boasts an increased capability of upper zone detection (in elevation and altitude), that enables it to detect and track air targets flying on ballistic and aeroballistic trajectories. It also features high jamming immunity, high degree of automation in operation control, low operation costs and comfort in handling.
