Unmanned aerial vehicle (UAV) landing marker responsive to radar signals

An unmanned aerial vehicle (UAV) landing marker that absorbs incoming radar signals emitted by a UAV and/or disperses reflected radar signals. The absorption and/or dispersion of the radar signals creates a reduced radar return in comparison to the environment about the landing marker. The UAV can d...

Beschreibung
Zusammenfassung:	An unmanned aerial vehicle (UAV) landing marker that absorbs incoming radar signals emitted by a UAV and/or disperses reflected radar signals. The absorption and/or dispersion of the radar signals creates a reduced radar return in comparison to the environment about the landing marker. The UAV can detect the area of reduced radar return and determine that it is a landing marker. Additionally, the UAV can determine a position of the landing marker relative to the UAV, based on the reduced radar return, to effect delivery of an item by the UAV. The landing marker can include materials, structures and/or features to absorb and/or disperse radar signals to cause the reduced radar return.
