OSA-P, the modernized SA-8 air-defense missile system on
the wheeled chassis BAZ-5937 |

The
Polish army continues to use the russian anti-aircraft defense
system SA-8, while passing by a modernization allowing to
answer the new threats and combat missions. The modernized
SA-8 anti-aircraft missile system combat vehicle 9A33BM
OSA-P is designed to destroy the aircrafts, helicopters,
rockets and other air targets in good and limited visibility
conditions, using of radio location or optoelectronics system
and Automatic diagnostic system.

The
modernization advantages:
- Day and night target tracking with small cloudiness to
the distance of 30 km – using the optoelectronic system,
with average cloudiness to 20 km with automatic tracking
– using video tracker.
- The distance measurement (using the laser rangefinder)
to the target like TS ISKRA, SU22:
* to 6 – 9 km (operating on the height up to 1,000
m)
* to 10 – 15 km (operating on the height above 1,000m
- The distance measurement (using the laser rangefinder)
to the target moving with very small speeds and the helicopters
– up to 20 – 25 km
- The qualification of the own position with exactitude
not smaller than 30 m
- The enlargement about at least 30% maximum distance of
detection of targets with the small effective reflection
surface. Enlarge the coefficient of the strengthener of
the receiving track above 6 dB and the coefficient of the
hums of the receiving track was lowered, about at least
2dB. The probability of correct detection grew up and the
probability of the false alarm got smaller
- The engagement about at least 10dB of suppression of passive
jamming and non-synchronic signals. Suppression of the jamming
of passive signals proceeds in the whole range of searching
radar (previously up to 35 km, at present up to 45 km),
for target tracking radar in the whole range (previously
– 1,5 km, at present up to 28 km)
- The improvement of the firing parameters in the conditions
of strong active jamming with use of the optoelectronic
system. The modernized SA-8 missile combat vehicle PRWB
OSA-P devices make possible the passage from video tracker
passive tracking on radio locating tracking and the life
firing can be conduct in the basic kind of the work. The
modernized SA-8 missile combat vehicle PRWB OSA-P devices
make possible speed steering of the target tracking radar
column in the PA mode from Beta (in the azimuth) and Epsylon
(in the elevation) knobs; that is why the life firing can
be conduct in the basic kind of the work “Semi-automatic”.
