General Dynamics Demonstrates Miniaturized Software-Defined Radios for Defense
Applications

SCOTTSDALE, Ariz. — July 25, 2003 — General
Dynamics Decision Systems recently demonstrated
innovative prototypes of “small form-fit”
software-defined radios that can fulfill multiple military
communications functions and are small enough to be
integrated into miniature robotic devices or the body
electronics worn by soldiers.
The demonstration emphasized that
software-defined radio technology can improve
interoperability among military services, coalition
partners and public safety officers, and solve
bandwidth problems, while reducing the number
of radios required to accomplish those objectives.
It was performed for DoD personnel active in
support to the U.S. forces tactical
communications. The radios demonstrated are
smaller than 22 cubic inches and weigh less than
 two pounds and can send and receive multiple
waveforms.

One example demonstrated was a prototype personal digital assistant (PDA) that can
be used by the
military to interoperate with public safety agencies. The PDA system was developed
in collaboration
with Vanu, Inc., an industry leader in the development of commercial software
radio waveforms.
“We’ve gone from racks of equipment to handheld devices to miniaturized,
embeddable
components,” said Chris Brady, director of Assured Communications for Decision
Systems. “Most
small devices, like cell phones, run only one or two waveforms. By taking a fresh
look at how our
software radio technology can exploit the latest hardware, we’re showing that a
single small device
can perform the functions of many, while still being cost-effective and
power-efficient,” said Brady.
JTRS Cluster 5, a future phase of the Joint Tactical Radio System program, is
expected to include
requirements for miniaturized software-defined radio technology in platforms such
as unattended
ground sensors, Land Warrior soldier systems, unmanned aerial vehicles,
intelligent munitions and
missile systems (non-line-of-sight launch systems).

General Dynamics also demonstrated a radio that can transmit and receive tactical
(SINCGARS),
AM, FM and satellite-communication waveforms. Designed to be part of the body-worn
electronics
embedded in soldier gear, the radio eliminates the need for multiple communication
devices to access
varied radio bands.
