ISR assets that are available. In general,
there are never enough sensors to satisfy all
of the PIRs. Traditionally, collection plans for
separate sensors are developed independently.
However EMS is supporting the
Horizontal Integration Enterprise Campaign
in the development of algorithms for collaborating
across sensors to develop a more
optimized collection plan.
The individual sensor schedules are sent to
each collection asset for action. In the EMS
scenario, a number of diverse sensor assets
are available for consideration in the analysis,
including EO/IR satellites, Global Hawk,
Predator, JSTARS and conceptual assets like
Space Based Radar and E-10A.
Intelligence is collected and “fused” into a
common operational picture (COP). The
COP includes imagery with targets identified
by automatic target recognition, as
well as tracks of moving targets.
The COP is analyzed manually by an operator-in-the-loop,
or semi-automatically by

Principal Software
Engineer, RTSC
Stanley Allen has
supported Raytheon’s
Enterprise Modeling
and Simulation (EMS)
program since 2003.
During these three years, he has been
afforded tremendous opportunities for
professional growth. For example, he led
the technical team for the ExCon and
RHIND (Run-Time HLA Interactive Network
Display) tools that discovered innovative
solutions to the control and monitoring
of large-scale simulations composed of
disparate elements.
In a program like EMS, Stanley sees cooperation
as the key to success, no matter what
the size of the organization. As such, he
encourages everyone to share their solutions
whenever possible.

experimental algorithms under development.
One of the outputs of this analysis is revised
priorities for the PIRs, reflecting, for example,
changes in strategy as a result of the warnings
generated by the convoy activity.
These priorities are re-input to the sensor
planning activity … and the process continues.
The purpose of the EMS experiment is
to measure the effectiveness of various sets
of sensors and their planning policies in
providing persistent surveillance.
As the amphibious vehicles depart the coast
for the island, it becomes imperative to
determine the intentions of the approaching
force, whether they be hostile or otherwise
(conducting a training exercise, for
example). A key piece of information is
subsurface surveillance.
In our experiment, contributing to maritime
persistent surveillance are notional sonar
models provided by a modified version of
High Level Architecture (HLA)-compliant
Fleet Command Naval Warfare Simulation
(developed by Sonalysts, Inc., and modified
Prior to EMS, Stanley spent 12 years working
on the software infrastructure for the
International Space Station Training Facility
(SSTF). In his work with the International
SSTF, Stanley had the opportunity to teach
Russian software engineers about the SSTF
architecture, integrate their code into the
trainer, and travel to Moscow to deploy the
SSTF software and hardware infrastructure
and its development tools.
Stanley’s work on the International SSTF
gave him valuable experience integrating a
variety of elements (simulation software and
tools from many U.S. companies and
numerous international partners) under a
central architecture. Integration has proven
to be crucial to the success of EMS as well.

by Raytheon). These sensor models provide
detection information to modified tracking
models used in ground surveillance described
above. In the scenario, these sonar models
show a mainland submarine underway.
The presence of the submarine indicates a
more provocative activity than a mere training
exercise. Should the submarine alter
course toward the island, the task force
commander, incorporating what is known
from the other ISR assets of the convoys
and military buildup, can take the appropriate
course of action.
Several measures of effectiveness have been
instrumented for run-time data collection to
support analysis and solution development:
Persistent Surveillance (geographic/temporal)
– Detection time
– Identification time
– Number of TCT tracked
– Track lock time
Sensor/Platform Performance
– Air/space/ground/subsurface
– SAR
– EO/IR

Enoch Arya draws
on both his attention
to detail and
his penchant for
the big picture. His
ability to look at
projects from all
perspectives helps
him ensure that
EMS continues to deliver industry-leading
solutions.
Another of his strengths is his passion for
improving collaboration and managing
knowledge. “The team has done much to
bring the various expertise together to
achieve our current capability,” he said.
“However, we have a ways to go to achieve
true One Company status.”
