PASADENA, Calif. -- NASA and the U.S. Department of
Homeland Security are collaborating on a first-of-its-kind portable
radar device to detect the heartbeats and breathing patterns of victims
trapped in large piles of rubble resulting from a disaster.
The prototype technology, called Finding Individuals for Disaster and
Emergency Response (FINDER) can locate individuals buried as deep as 30
feet (about 9 meters) in crushed materials, hidden behind 20 feet (about
6 meters) of solid concrete, and from a distance of 100 feet (about 30
meters) in open spaces.
Developed in conjunction with Homeland Security's Science and Technology
Directorate, FINDER is based on remote-sensing radar technology
developed by NASA's Jet Propulsion Laboratory in Pasadena, Calif., to
monitor the location of spacecraft JPL manages for NASA's Science
Mission Directorate in Washington.
"FINDER is bringing NASA technology that explores other planets to the
effort to save lives on ours," said Mason Peck, chief technologist for
NASA and principal advisor on technology policy and programs. "This is a
prime example of intergovernmental collaboration and expertise that has
a direct benefit to the American taxpayer."
The technology was demonstrated to the media today at the DHS's Virginia
Task Force 1 Training Facility in Lorton, Va. Media participated in
demonstrations that featured the device locating volunteers hiding under
heaps of debris. FINDER also will be tested further by the Federal
Emergency Management Agency this year and next.
"The ultimate goal of FINDER is to help emergency responders efficiently
rescue victims of disasters," said John Price, program manager for the
First Responders Group in Homeland Security's Science and Technology
Directorate in Washington. "The technology has the potential to quickly
identify the presence of living victims, allowing rescue workers to more
precisely deploy their limited resources."
The technology works by beaming microwave radar signals into the piles
of debris and analyzing the patterns of signals that bounce back. NASA's
Deep Space Network regularly uses similar radar technology to locate
spacecraft. A light wave is sent to a spacecraft, and the time it takes
for the signal to get back reveals how far away the spacecraft is. This
technique is used for science research, too. For example, the Deep Space
Network monitors the location of the Cassini mission's orbit around
Saturn to learn about the ringed planet's internal structure.
"Detecting small motions from the victim's heartbeat and breathing from a
distance uses the same kind of signal processing as detecting the small
changes in motion of spacecraft like Cassini as it orbits Saturn," said
James Lux, task manager for FINDER at JPL.
In disaster scenarios, the use of radar signals can be particularly
complex. Earthquakes and tornadoes produce twisted and shattered
wreckage, such that any radar signals bouncing back from these piles are
tangled and hard to decipher. JPL's expertise in data processing helped
with this challenge. Advanced algorithms isolate the tiny signals from a
person's moving chest by filtering out other signals, such as those
from moving trees and animals.
Similar technology has potential applications in NASA's future human
missions to space habitats. The astronauts' vital signs could be
monitored without the need for wires.
The Deep Space Network, managed by JPL, is an international network of
antennas that supports interplanetary spacecraft missions and radio and
radar astronomy observations for the exploration of the solar system and
the universe. The network also supports selected Earth-orbiting
missions.
