Researchers at Sandia National Laboratories created a detection system that combines four generic sensors with a more sophisticated, custom-built sensor.

"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.
