Title: Novel Automotive Radar Using 3D Printed Luneberg Lens


Invention: This technology employs a 3D printed Luneburg lens and array and adaptive sensing techniques to provide greater autonomous radar coverage. Combined with the adaptive sensing technique, this technology will allow radar systems to adaptively adjust their spatial sensing patterns and sweeping frequency bands to improve scanning efficiency, avoid interference from intruder radar systems and cover a 360 degree scanning angle.


Background: Technologies like LIDAR and Advanced Driver Assistance Systems (ADAS) are currently in use for autonomous automotive radar. Unfortunately, these systems require expensive sensors with limited range and sensitivity to adverse weather conditions. The 3D Luneburg lens presented here uses a gradient index lens, which is used for wide angle scanning and multiple beam tracking. In addition, this technology uses additive manufacturing techniques, which, when compared to conventional methods, create a faster, more convenient, and less expensive lens that is capable of implementing millimeter waves of 30 to 300GHz.
