Human-technology interaction for standoff IED detection
2011
IEDs kill our soldiers and innocent people every day. Lessons learned
from Iraq and Afghanistan clearly indicated that IEDs cannot be detected/defeated by
technology alone; human-technology interaction must be engaged. In most cases, eye
is the best detector, brain is the best computer, and technologies are tools, they must
be used by human being properly then can achieve full functionality. In this paper, a
UV Raman/fluorescence, CCD and LWIR 3 sensor fusion system for standoff IED
detection and a handheld fusion system for close range IED detection are developed
and demonstrated. We must train solders using their eyes or CCD/LWIR cameras to
do wide area search while on the move to find small suspected area first then use the
spectrometer because the laser spot is too small, to scan a one-mile long and 2-meter
wide road needs 185 days although our fusion system can detect the IED in 30m with
1s interrogating time. Even if the small suspected area (e.g., 0.5mx0.5m) is found,
human eyes still cannot detect the IED, soldiers must use or interact with the
technology - laser based spectrometer to scan the area then they are able to detect and
identify the IED in 10 minutes not 185 days. Therefore, the human-technology
interaction approach will be the best solution for IED detection.
