FIELDING COGNTIVE EW TECHNOLOGY
Developing an understanding of what
cognitive EW technology is provides a
better sense of the many ways it can be
integrated into EW systems. At its most
basic level, cognitive EW technology can
be fielded in today's EW systems with
relative ease. For instance, algorithms
developed for DARPA's Adaptive Radar
Countermeasures (ARC) program have
been programmed into the US Navy's ALQ214(V)4/5 RF Countermeasures (RFCM)
system. This simple upgrade offers some

performance improvements in the EW system, but future EW systems built around
cognitive EW technologies are expected
to deliver much better performance. In
order to realize these advantages however, future EW systems will need to provide
more than cognitive EW algorithms and
better data processing. According to Szumowski, "There's a tighter interconnect
between backend adaptive algorithms
and the frontend resource management.
Adaptive EW systems need to operate on
a different quality of receiver data than

traditional systems, thus requiring the
need to adjust resources. They also may
need to respond in a specific timeline
(i.e., to target pulse-on-pulse for radar
or specific control channels for comms)."
His colleague, Greg Patschke adds, "There
is more than just comparing raw signal parametric data to onboard mission
data files."
Kilfoyle says, "Existing cognitive EW
systems are at relatively low technology
readiness levels and complete reference
architectures are still being considered.

technology, but that the EW community "must take caution around the deep
learning buzz. It provides great benefits in terms of static classification
without too much upfront engineering. However, it's not a silver bullet
and needs to be paired with traditional approaches and domain expertise to
be useful operationally. I can't stress
this enough."
Raytheon's Kilfoyle adds, "Networking technologies that support EW collaboration between platforms may also
be a key feeding technology. As we continue down the path of the convergence
of EW and cyber, there may be important
contributions to cognitive EW capability
as well."
Another broad trend that is supporting cognitive EW technology is the DOD's
push toward multi-function systems.
Tremper describes this as "migration of
system designs toward multi-function
operations with wideband and digitally
tunable analog components for receivers and transmitters, as well as the
application of computational and machine learning approaches toward spectrum assessment, prediction and access
optimization."
Aside from these general technology
trends in defense electronics, there are
also some specific EW technology trends
that are supporting cognitive EW. Szumowski says, "Modern EW systems are
now providing the ability to operate on
'pre-detection' data (IQ) which enables
more advanced upfront signal recognition." Rosenwinkel adds, "This is shifting the differentiating aspects of EW
systems from better RF hardware to
better digital processing hardware and
advanced algorithms."
