Another important aspect of future
AEA is missions is the ability to find
emitters that operate in the background
noise (i.e., below the noise floor) of an
electromagnetic environment. Advanced
IADS already feature AESA radars and
low-probability of detection C2 datalinks
that use frequency hopping and direct
sequence spread-spectrum techniques to
operate at very low power levels, which
make it difficult for AEA platforms to detect them from stand-off ranges. These
are not new technologies for western radars and radios, but they represent a relatively new challenge for AEA platforms.
Bryan Clark a senior fellow at the
Center for Strategic and Budgetary Assessments (CSBA) in Washington, DC,
has described this growing use of lowpower spread spectrum technologies as
the "power-control regime" in electromagnetic spectrum operations. Clark is
co-authoring a CSBA study on future
EW trends that will be released early
next month. In the past, the contest
between IADS and AEA has been primarily characterized by detecting and
defeating emitters that operate above
the noise floor. Radar and C2 transmissions that stood out were easier to
identify and locate, and could usually be
jammed with high-power AEA platforms
operating from stand-off ranges. Now
the traditional "high-power" regime is
evolving into the power-control regime,
in which AEA platforms must find radar
and communications emitters that operate in the background noise of an electromagnetic environment. This calls for
more sensitive, wideband ESM receivers
with the processing power to detect and
monitor these wideband, low power signals. It also requires smarter, more agile
jammers that can generate low-power
signals that blend into the background
noise. These AEA technologies have
been in development for more than a
decade, and they are becoming the new
standard for AEA operations. Over the
next two decades, the challenge will be
to further develop these receiver and
jammers to fit small UAVs and decoys
that can perform close-in jamming.
While there is a clear trend toward
"power control" in the AEA vs. IADS contest, EW is also focusing on the development of high-power electromagnetic
