A Doppler Effect Based Framework for Wi-Fi Signal Tracking in Search and Rescue Operations.
IEEE Transactions on Vehicular Technology(2018)
摘要
We consider rescue missions in postdisaster scenarios with particularly difficult environments where no infrastructure is available. Given the increasing popularity of smartphones and wearable devices, this paper proposes a rescue system which uses the Doppler effect to determine the direction of Wi-Fi signals emitted from disaster survivors' mobile devices to help rescuers quickly locate the surv...
