A power transmission and imaging system for an airship comprises a
transmission antenna array configured to transmit an energy beam to a
patch rectenna carried by the airship. Coupled to the patch rectenna is a
power distribution and control network that supplies rectified power
delivered by the energy beam into the proper format for delivery to a
power storage system and a motor control system. The power storage system
comprises one or more batteries to store the transmitted energy, while
the motor control system powers various propellers, blowers, and valves
maintained by the airship in order to descend the airship to the ground.
The rectenna may also function as an imaging system in real-time. The
image processing system uses the patch rectenna to transmit and receive
signals, and in turn store and process the return signals (images).
