What mechanism does the RECCO system use to detect a missing person?
Answer
Microwave signals sent to passive reflectors
The RECCO system operates by utilizing a handheld or airborne detector that emits a microwave signal into the environment. When these waves encounter the specific passive reflectors integrated into ski gear or avalanche equipment, they bounce back as a distinct signal. This interaction allows rescuers to identify the presence of a person without the victim needing to activate any battery-powered devices, as the technology relies entirely on the reflective properties of the hardware worn by the individual.
