Multiple magnetic sensors were networked in a configuration
to detect, track, and classify non co-operative targets.
Most of the development was supported by the DARPA contract
"MAGNETIC ARRAY." A novel system for real-time
data acquisition and analysis has been developed for various
tests and system optimization. The real time system (Advanced
Digilyzer) described below has been used for field test,
data acquisition, real-time tracking, and characterization
of various non-cooperative targets.
CRS Magnetic Tracking Software
This Windows® 95-based system uses Digital Signal Processors in conjunction
with the host processor to acquire and process magnetic
data. The system can track vehicle movement in real time,
with graphic displays of raw data as well as vehicle tracks.
It provides tracks and classifications based on induced
field perturbations. Residual fields need to be modeled.
The system relies on a pair of Analog Devices SHARC DSP
chips to perform the analysis necessary to calculate the
vehicle position in real time. The host processor handles
plotting and data logging in addition to managing the
DSPs.
Real-time position location using
tri-axial magnetic sensors.
-
SHARC processors’ fast calculations
for multiple sensors.
-
Real-time plotting of raw data and
vehicle tracks.
-
Proprietary algorithm to calculate
position, velocity, acceleration, and magnetic moments.
-
Graphical User Interface and Windows® 95 interoperability for ease of use.
-
Logging of data to disk for further
analysis and review.
Uses multiple sensors (currently up to
six) in integrated array for improved performance.
