The F-35 EODAS uses multiple large format sensors to provide high resolution infrared imagery for aircraft situational awareness and.
Su-35S Stealth Fighter Pilot Action
The core of the Su-35 armament is a new radar control system with a phased antenna array (Irbis-E). It features unique capabilities in terms of the target detection range. This is a development V V Tikhomirov Research Institute of Instrument Production. In design, this is an X-waveband multi-role radar with a passive Phased Antenna Array (PAA) mounted on a two- step hydraulic drive unit (in azimuth and roll). The antenna device scans by an electronically controlled beam in azimuth and angle of elevation in sectors not smaller than 60°. The two-step electro-hydraulic drive unit additionally turns the antenna by mechanic means to 60° in azimuth and 120° in roll. Thus, in using the electronic control and mechanical additional turn of the antenna, the maximum deflection angle of the beam grows to 120°.
