OSA AIMING RADAR
COMPLEX
The Osa aiming radar complex is
intended for equipping the
MiG-29-type aircraft. The Osa
phased-array radar complex,
ensuring electronic scanning and a
wide-zone (with a cone angle
of 120
o
) guidance of active, semi-
active and infrared-homing mis-
siles, is capable of simultaneously
tracking eight targets and engag-
ing four of them throughout the entire angular zone and
16 in the scanning zone, as well as combining the air-
to-air and air-to-surface operating modes.

BARS RADAR WEAPON
CONTROL SYSTEM
The Bars radar weapon control system is
intended for equipping the Su-35, Su-37
and Su-30MKI aircraft.
Bars is a multifunction multirole radar
system with electronic beam control. Its
main features, enabling it to outperform
other similar radar systems, are as fol-
lows:
- use of a phased array with a mechani-
cally-corrected turn. The single-gimbal
(azimuth) and two-gimbal phased arrays
are developed;
- use of a high-gain and low-side lobes
phased array;
- provision for a powerful transmitting
channel output amplifier built around the
Chelnok travelling wave tube boasting an average
power of 5 to 7 kW and a duty cycle of 4, having no
analogs in the world.
