effectively harnessing the full benefits
of SIGINT technology often requires
high-fidelity stems which can be prohibitively expensive. Says his colleague,
Liivet, "Even though a lot of nations are
looking at border security (and the use of
SIGINT) in a new, higher-priority light,
they don't have the spending capacity
to do that. Borders can be extremely
large. In India, for example, we're talking 21,000 km. How do you monitor that
much territory across all the various frequency bands of interest?"
Liivet says one alternative is the
selective use of SIGINT systems as a
complementary technology to identify
and geolocate threats that can then
cue other sensors. "So, you don't need
to buy 1500 km worth of SIGINT systems, you just need to have the ability to get that SIGINT capability in the
time and a place that you need it. It's
looking at where the threats are, and
how to best deal with them. Do we need
SIGINT? Yes we do, but do we need it
everywhere? Probably not." Liivet says
the approach allows a nation to reduce
its overall cost and get something in

place quickly. "Later, they can perhaps
expand to a better, higher-fidelity system, depending on what they are trying to achieve."
LS Telcom offers its "LS Observer"
surveillance and data collection system
to serve in this role. The system is a
mix of fixed, portable and transportable
spectrum monitoring equipment that
collects intelligence information from,
and provides geolocation of, suspicious
emitters. In addition to border protection, the system is also used in other
applications such as VIP protection, and
providing security for critical infra-

structure sites and other types of secure
installations. Capable of autonomous
and unattended operation, systems
range from small man-portable unit, to
transportable and fixed units.
As described by Ross, "Basically,
with the LS Observer system we're able
to survey or monitor the radio spectrum over a long period of time. So, if
you have a continuous spectrum picture that looks the same over a period
of time, you can use that as a baseline
'mask.' At the same time, we also provide a software system that is able to
simulate radio emissions. So we don't
just take the spectrum mask that we
collect, we can also say 'is this mask in
line with what we would expect from
the radio stations that are supposed
to be on air, or is it not.' So, we have
correlation capabilities between data
that has been monitored and propagations that are made based on license
data that is available. Then, if a signal
is found that we've not heard in the
past, we can categorize it as a potential
threat and use geolocation to pinpoint
where it is coming from."
