|Data analysis from a Sandia in-house customized sensor, showing advanced pattern recognition identifying an SUV compared to a person. The large sophisticated sensor is supplemented by small, low-cost, low-power, commercially available sensors.|
|Sandia researchers hold a Labs-designed sophisticated sensor that interacts with smaller off-the-shelf sensors like those seen in the foreground. |
"We wanted inexpensive sensors to act as a first line of defense to identify potential targets and wake up the unattended ground sensor package. The package then could use advanced pattern-recognition to classify four-legged animals, two-legged humans, or civilian and military vehicles," says Hong Nguyen, head of the research team. The use of the powerful sensor with the smaller ones increases detection range, lowers false alarms, and increases the area of coverage per dollar spent in complex terrains.
