RADARS

AB8>=::
The radar set comprises:
- vehicle M1 carrying the antenna assembly, recep-
tion/transmission equipment and built-in ground-based
radio interrogator;
- vehicle M2 carrying control, data processing, display
and transmitting equipment;
- vehicle M3 carrying SPT&A, test equipment and
cables;
- trailers towed by vehicles M1 and M2, carrying pow-
er generating systems.
Optionally, the radar can be provided with remote con-
trol equipment comprising four operator workstations
linked with the radar by a fiber-optic line when
deployed up to 1 km away from it, and by radio line
when located at a distance of up to 15 km.
The Gamma-S1E is a prospective air target detection
radar.
It is noted for high mobility, short deployment (close-
down) time, possibility of operation from a trench or
embankment, high energy potential and jamming
immunity, and high degree of automation of target
detection and dynamic parameter measurement, sys-
tem operation control and monitoring.
The radar stably works at ambient temperatures of
±50
o
C, relative humidity of up to 98% and wind velocity
of up to 25 m/s. The maximum elevation of the radar
site above sea level is 2,000 m.
