The Defense Advanced
Research Projects Office (DARPA) supports an active
program of research on Internetted Unattended
Ground Sensors (I-UGS). SenTech is working with
DARPA under an SBIR contract to develop advanced
acoustic and seismic algorithms for target detection,
localization and identification. SenTech has built
and field tested several sensor units based on COTS
components. SenTech is also developing
acoustic-seismic sensors that can be deployed using a
40 mm grenade launcher. A new low-power Digital
Signal Processor for this mission has been developed
and tested.
The Unattended
MASINT Sensor (also known as Steel Rattler and
its air delivered version, Steel Eagle) combines the
ability to detect and track targets at extended
ranges with superior target identification
capabilities. Under contract to Sandia National
Laboratories, SenTech has provided the design of all
signal processing algorithms and the software to
implement them. This sensor has been successfully
tested during the most recent Roving Sands exercise
and in a variety of government sponsored tests.
The Acoustic
Warning System - Integrated Sniper Location System
is an easy to deploy, highly accurate sniper location
systems developed under contract for Lockheed Martin
Loral Infra-Red and Imaging Systems and the Defense
Advanced Projects Agency (DARPA). The AWS gained high
marks for accuracy during government sponsored tests
at the USMC Camp Pendleton MOUT (urban environment)
training facility.
SenTech has been
funded for several SBIR projects in the area
of acoustic and seismic sensing. For the US Army Tank
- Automotive Command (TACOM), SenTech developed an
acoustic sensor capable of implementing sophisticated
array processing techniques (beamforming) to detect
and track combat vehicles at extended ranges. For the
US Army Armaments Research, Development and
Engineering Center (ARDEC), SenTech developed a new
approach for target classification and identification
that combines artificial intelligence techniques with
statistical pattern recognition algorithms to achieve
a new level of target classification and scenario
interpretation performance.
SenTech has supported
the US Navy Naval Underwater Warfare Center in two
field trials (1996 and 1997) sponsored by the Joint
Acoustic Sensor Measurement Program. These test
involved the design and test of a planar hydrophone
array used to track towed acoustic sources and
targets of opportunity. Tests of this system were
carried out during the summer of 1996 and 1997.
SenTech has done
consulting and design work for Textron Defense
Systems, Lockheed Martin Loral Infrared and Imaging
Systems, the Northrop-Grumman Corporation, IITRI,
SAIC, Allied Signal, the US Army ARDEC, and the US
Marine Corps. .
