P-18-2 MOBILE
METRIC-WAVE
2-D RADAR
Designed to detect, identify and track air targets, includ-
ing «stelth» threats, at long ranges and transmit their
range, azimuth and elevation data to indicators and oth-
er radar-interfaced devices.
The radar antennas, its basic equipment and the diesel
electric
power plants
are carried by two cross-country
trucks and two trailers. The radar can be powered by
industrial mains.
The radar has a remote control workstation, which can
be set up at a distance of up to 500 m from the radar to
monitor the air situation, con-
trol radar systems operation,
and handle information traffic.
The radar has been upgraded
with a high-power active noise
jamming rejection (ANJR)
equipment. Other enhance-
ments include replacement of
the passive-noise analog pro-
tection system with a DMTI
system, as well as replacement
of some tube-based units with
semiconductor components.
The ANJR system includes
independent channels of auto-
matic noise compensation, which provide protection
against active noise jamming with a maximum total power
of 200 W/MHz and an equivalent range of 200 km.
The DMTI system enhances the effectiveness of the
passive-noise, ground clutter and nonsynchronous jam-
ming protection system.
To equip the P-18-2 radars with the ANJR and DMTI
systems, complete upgrade kits are available.
