Key result
A continuous-wave microwave transceiver successfully detected human breathing through a 1.8-m-thick snow barrier and a 1.2-m-thick igloo roof to simulate avalanche entrapment.
Why the study?
Can a continuous-wave microwave transceiver detect breathing and heartbeat in people buried in snow?
Can a continuous-wave microwave transceiver detect breathing and heartbeat in people buried in snow?
A continuous-wave microwave transceiver can detect breathing and heartbeat through thick snow, suggesting potential utility for avalanche rescue.
May support microwave-based avalanche rescue prototypes; leaves open real-world validation and integration.
The potential of a continuous-wave microwave transceiver as a tool for detecting breathing and heartbeat of people buried in snow has been experimentally evaluated. The breathing has been clearly detected through a 1.8-m-thick snow barrier as well as through the 1.2-m-thick roof of an igloo dugout to simulate the experimental conditions of a human being trapped under an avalanche.
