including tactical ones, another Israeli company,
RADA, has entered the market with a line of similar
systems, which it has successfully exported --
including to the US.
The company offers two families of radars -- the
Compact Hemispheric Radar (CHR) and Multi-
mission Hemispheric Radar (MHR) Families. The
CHR can be used for vehicle active protection, while
some of the MHR variants provide ground based
air defense, supporting VSHORAD missiles, and
providing C-RAM early warning for mobile forces.
Employing modern Active Electronically Scanned
Array (AESA) antennae technology, these radars
provide extremely fast volume coverage performing
target search, classification and tracking. Innovative
angular measurement techniques are used to
overcome the small antenna size, along with Pulse-
Doppler processing and digital, adaptive beam
forming, enabling a single radar to monitor a wide
range of threat velocities.
By electronically steering multiple beams
the radar performs track-while-scan over a full
hemispheric coverage, including very high elevation
angles required for ballistic trajectory calculations of
typical RAM targets. It also provides real-time range
and angle measurement required to support active
protection systems (APS).
These software controlled radars offer beam
forming to control the spatial coverage, order of
beams and their waveform, to tailor the radar for
multiple missions either as a dedicated system or an
'all in one' sensor, interleaving several missions over
certain periods of time. Switching between missions
can be manual or programmable and predefined
upon real-time events.
APS are installed on armored vehicles and
provide protection against rocket-propelled
grenades (RPG), anti-tank guided
missiles (ATGM) and tank shells. At the
heart of the APS are search and track
radars with the ability to detect threats
and enable interception before a threat
strikes the vehicle. The addressable
APS market in the Western World is
estimated in the tens of thousands of
vehicles, implying a multi-billion dollar
market potential for tactical radars that
can perform such functions.
RADA's Compact Hemispheric
Radar (CHR) platform, developed to
address the needs of the APS market,
is an S-band, software-defined, pulse-
Doppler, active electronically scanned
array radar. The system introduces
sophisticated beam forming capabilities
and advanced signal processing,
which can provide various missions
on each radar platform and offers an
ratio. It is compact and mobile, enabling
hostile fire detection capabilities for
combat vehicles and providing critical
targeting information for APS.
Dov Sella, RADA's CEO, said that the active
protection market is growing fast. He pointed
out that the company's CHR is incorporated into
IMI Systems' "Iron Fist" family of APS, and has
undergone hundreds of live fire tests. Recently
RADA delivered CHRs to to the US company Artis,
to be integrated and tested with its "Iron Curtain"
Sella added that the active protection market
is expanding: "The global APS market is gaining
strong momentum; we believe that as a result, new
and significant business opportunities will come
across RADA in the near future."
Sella revealed that late last year, BAE Systems
announced the award of a contract by the Dutch Army
for the testing and verification of the IMI's "Iron Fist "
APS for its CV90 tracked Infantry Fighting Vehicles: "It
will be the first NATO combat vehicle to receive APS
which includes our technology. Furthermore, recent
publications in the US press indicate the intention of
the US Military to test and evaluate Active Protection
Systems for its tanks and Armored Fighting Vehicles.
Hence, we are excited with our potential and look
forward to strong growth in our APS tactical radar
sales over the coming years."
Sella revealed that the "Red Color" detection
systems that give Israelis that live near the Gaza
strip a very short alert on incoming mortar shells is
based on RADA's technology.
