NASA introduces radar to help detect buried survivors

NASA has introduced a new radar detector that will help detect buried victims under the rubble of buildings in disaster.

NASA experts working with the Department of Homeland Security (DHS) demonstrated the device's model to the press in Washington on Sept. 25, according to AFP.

According to NASA, the handheld device called FINDER (meaning 'seeker'), which stands for Finding Individuals for Disaster and Emergency Response , The victims live up to 9 meters deep under rubble.

In cases where the victim was buried under concrete, FINDER's detection range was reduced to 6m, but in open space (without obstacles), the device could detect people from a distance of 30m .

John Price, director of the emergency response program at DHS's Department of Science and Technology, said FINDER's goal was to help emergency rescue workers ' be able to rescue victims in a meaningful way. in disaster '.

NASA says the new technology is more advanced than the old-fashioned radar, which could not detect a buried person in a dilapidated building as the signal was flushed between layers of rock.

FINDER used the algorithm 'to isolate the smallest signals from one's chest movement by filtering other signals, such as signals from moving plants or moving animals.'

A similar technology is also used by NASA to detect spacecraft in its Deep Space Network.

"A light signal will be sent to the space ship and the time it takes to return the signal will help determine how far the ship is," NASA explained.
