BARS Airborne Radar Control System
The BARS airborne radar control system together with the airborne equipment of the aircraft ensures:
Provision of information on tactical environment in the aircraft front-line hemisphere while tracking-down both ground- and water-based targets;
Simultaneuous firing of several targets (depending on the missile type) in the long-range combat mode;
Missiles firing of a separate target in the short-range combat mode;
Use of weapons of the "air-to-surface" type together with the other aircraft of the system;
Control over the aircraft flight while conducting military operations at air, marine and ground-based targets;
Comprehensive processing of data received from various aircraft systems and other aircraft in order to enhance the efficiency of the aircraft military use;
Informational support for aircraft airborne systems;
Identification of inter-related air targets types;
Evaluation of equipment and weapons condition at all stages of ground-based preparation and during flights.
