a Compact Integrated Defensive Aids Suite (CIDAS) installed in
a standard BOZ pod. It carries an Electronic Warfare Controller
(EWC), five BOPL-39 pyrotechnical dispensers, and MAW-300
ultraviolet-band missile warners.
The Eurofighter Typhoon, which are equipped with the
Praetorian Defensive Aids Subsystem (DASS), have three Active Matrix LCDs to present information to the pilot (including
EW), which eliminates the need for a separate indicator and
controls. Sensor fusion was part of the concept from day one.
According to the "no need no show" philosophy, the system
automatically selects the information that is truly needed in a
given situation, like a threat warning display, EW action and
options. Eurofighter's unique Voice Throttle and Stick (VTAS)
system, which includes Direct Voice Input (DVI) allows access
to DASS as well. As the system was designed from early on to
cover lower-band (surveillance) emitters in addition to other
radars in the IADS kill chain, the potential contribution to situational awareness and offensive missions are clear. As a special case of integration, the fighter's EW system compensates
angle of arrival information for wing flexing, as DASS pods
are located out on the wingtips. This latter example shows the
practical difficulties in integration: for a similar reason, MAWS
sensors have certain limitations as to where they can be fitted
without hindering their performance.
While Soviet-Russian fighter design always emphasized
multi-sensor, multi-channel targeting, including combined
modes (consider the weapons system of the MiG-29, including
radar, IRST, laser ranging and helmet mounted sight channels),
their limited access to robust computing power and new sensor
technologies makes an integrated approach more difficult. Beside the T-50 fifth generation program, which has multi-band,
multi-aperture AESA radar technology, as well as all-around
electro-optical sensors, the 4+ generation Su-35 and new Su-30
variants also have MAWS in addition to their basic EW suite.
In China, besides images of emerging fifth-generation aircraft
like the J-20, 4+ generation platforms like the J-10B also show
new sensors with what is believed to be greater levels of suite
integration, but not a fused sensor picture for the pilot.

INFORMATION CONSUMERS BECOME
INFORMATION PROVIDERS
Through integration, fighters which were consumers of
battlefield information for most of the time in the past, can
become information providers, not just by improvement in
communications and networking, but also because of the
quality of the information they can put together by integrating their multi-channel, multi-band sensor suites and consolidating them onboard before sharing. If done appropriately,
this consolidated information can mean more than the sum
of the individual sensor channel's "raw" output. Whether the
comparative success of such efforts will be enough to keep
the fourth-generation platforms competitive on the market,
it is too early to tell. One thing is sure, however. If a move
to a new-generation platform is out of the question for budgetary or political reasons, fighter upgrades featuring new
sensors, their efficient integration and networking is still a
promising solution. a
