Abstract
An unmanned aerial vehicle (UAV) having at least one sensor for detecting the presence of a survivor in a search and rescue area. The at least one sensor is preferably an ultra-wide band (UWB) transceiver sensor. The UAV includes a UAV data link transceiver for wirelessly communicating information concerning the survivor to a command center.
Claims15
An unmanned vehicle (UV) comprising:
- an ultra-wide band (UWB) transceiver sensor including an S-band, multiple input multiple output (MIMO) phased array radar system to detect a presence of a survivor in a search and rescue area, the phased array radar system detecting heart rates and respiration rates to generate vital signs telemetry data;
- a sub-gigahertz UV data link transceiver to wirelessly communicate information regarding the survivor including the vital signs telemetry data detected from the S-band, MIMO phased array radar system to a command center, wherein a building controller located in a building associated with the search and rescue area relays the information between the UV and the command center;
- an inter-UV data link transceiver for wirelessly communicating information regarding the survivor to a second UV to refine the accuracy of the detected presence of the survivor by confirming, by the second UV, that the survivor was correctly detected and to receive, from the second UV, a detection message to the inter-UV data link transceiver based on a determination of the detected survivor;
- and
- a UV local positioning system module to:
- receive one or more local positioning signals from a plurality of local positioning system portable antennas surrounding the search and rescue area;
- determine a time delay of each of the one or more local positioning signals received by the UV local positioning system module, each time delay relative to a particular local positioning system portable antenna and calculated based on a time difference between transmission of a local positioning signal by the particular local positioning system portable antenna and receipt of the local positioning signal by the UV local positioning system module;
- determine a distance from the UV to each of a subset of the plurality of local positioning system portable antennas based on the time delay of each of the one or more local positioning signals;
- and
- determine a localized position of the UV in the search and rescue area based on the distance from the UV to each of the subset of the plurality of local positioning system portable antennas.

- and
- wirelessly communicating information regarding the survivor including the vital signs telemetry data and the localized position of the survivor to a command center via a sub-gigahertz data link transceiver, wherein a building controller located in a building associated with the search and rescue area relays the information between the unmanned vehicle and the command center;
- and
- wirelessly communicating information regarding the survivor to a second UV to refine the accuracy of the detected presence of the survivor by confirming, by the second UV, that the survivor was correctly detected;
- and
- receiving, from the second UV, a detection message based on a determination of the detected survivor.
