Laser Warning Systems Address
Increasingly Lethal Threats

The Journal of Electronic Defense | December 2013

By John Haystead

With the rapid proliferation of laser-based
target designation and ranging systems
on the battlefield, it should not come
as a surprise that laser detection and
warning systems have also necessarily
become more important and prevalent.
On the battlefield, lasers are used as
rangefinders, target designators, and in
their most lethal application, as guidance
systems for "beam-rider" missile systems.
To counter them, laser warning systems
have been installed on (or integrated into
other threat warning systems aboard),
a wide variety of airborne and groundbased platforms, naval vessels, and even
individual soldiers. In some cases, in
addition to alerting to a threat, laser
warners may automatically trigger some
form of countermeasure system such as
a smoke or aerosol screen, laser countermeasure ("dazzler"), laser jammer, or
basic counterfire.
As observed by Brian Gephart,
Senior Program Manager, ISR Systems,
UTC Aerospace Systems (Danbury, CT),

previously Goodrich ISR Systems, there's
been a steady proliferation of laser-based
threats over time, particularly in terms of
the more basic-technology, laser rangefinders where a number of products are in
fact readily available commercially. "Laser
rangefinders have become smaller, more
portable, cheaper, and thus much easier
to acquire, but there's also been increased
proliferation of more sophisticated laser
target designation technology beyond
what was once just the more advanced
militaries of the world - technology that
significantly increases the probability of
a target hit and kill."
Most worrisome, Gephart notes, is the
fact that advanced-technology beam-rider
missile threats, which are often difficult
to detect early enough for their target
to take evasive action, are also increasingly appearing on the stage - for example
turning up in the recent engagement
between Hezbollah and Israeli forces -
with the likelihood that these sophisticated weapon are also being sold into

other potential Middle-East hotspots. As
described by Bill Kasting, Vice President
and General Manager, ATK Defense
Electronic Systems Division (Woodland
Hills, CA), "the weapons that use beamriding technology are not only difficult to
detect but are also probably the most difficult to defeat, with the real goal being
to detect the enemy on the ground that
is trying to engage you before the weapon
is even launched."

SENSOR TECHNOLOGY
The core technology behind laser
warning systems are semiconductor photodetectors, such as PIN diode arrays or
cascaded/avalanche photodiode/phototransistor arrays. Phototransistors are
photodiode/amplifier combinations integrated within a single silicon chip that
provide internal gain, thus making them
