Abstract
The present invention extends to methods, systems, devices, and apparatus for landing guidance for remotely operated aerial vehicles using crossed radar beams. Radar units can be angled over a landing pad/dish for a Remotely Operated Aerial Vehicle. The Remotely Operated Aerial Vehicle lines up over radar beams by basically following radar beams to equalize the returned energy of each beam. The radar units facilitate lateral position tracking. When a Remotely Operated Aerial Vehicle is off to one side, returns for one or more beams may be stronger than returns for one or more other beans. When a Remotely Operated Aerial Vehicle is maneuvered to an appropriate position for terminal guidance, rotors can be turned off and/or thrust settled (e.g., to 90%).
