Abstract
An unmanned aerial vehicle (UAV) landing marker transmits a reply signal in response to receiving radar signals emitted by a UAV. The landing marker can include a passive transponder that emits the reply signal, with the reply signal being a harmonic of the fundamental frequency of the radar signal emitted by the UAV. The landing marker can also include a transmitter to transmit the reply signal. Additionally, the landing marker can include sensors to monitor the environment about the landing marker and this environmental information can be transmitted to the UAV as part of the reply signal.
