Abstract
The embodiments described herein provide radar systems for use on unmanned vehicles. The radar systems can be applied to a wide variety of unmanned vehicles, including unmanned aerial vehicles and unmanned land vehicles. In general, the unmanned vehicle comprises a housing having at least one propulsion motor, a radar processing unit coupled to the body, and an antenna. In accordance with the embodiments described herein, the antenna includes an antenna body defining at least one transmitting waveguide and at least one receiving waveguide coupled to the radar processing unit. The antenna body is formed from plastic and includes metalized surface. In one embodiment, the antenna body is formed from 3-dimensional (3D) plastic printing.
