Abstract
This project explores the integration of a Luneburg lens antenna with a commercial drone platform for directional radar sensing. Luneburg lenses, known for their passive beam-steering capability, provide a lightweight and cost-effective alternative to traditional radar systems. By leveraging the lens’s ability to focus electromagnetic waves through geometric design and material gradient, this system aims to provide effective and cost efficient radar sensing in airborne applications.
The antenna system utilizes an Infineon BGT60LTR13 radar module, controlled by a Raspberry Pi 4. A custom Python program was developed to collect raw radar data, store it locally, and stream the data wirelessly to a grounded device for processing. The system was housed in a lightweight 3D-printed PLA structure that ensures the radar module and Luneburg lens remain secured and aligned during flight.
This proof-of-concept system was mounted to the underside of the drone to test the practicality of combining compact radar hardware with beam-steering dielectric optics. While preliminary testing is ongoing, early efforts have demonstrated the feasibility of integrating this hardware configuration for aerial sensing.
Future work will focus on flight testing under varied environmental conditions, reducing system weight, and enhancing mechanical stability. Additionally, software improvements will aim to streamline data acquisition and processing, increase communication efficiency, and optimize the code for real-time operation. This work highlights the potential for low-cost, modular radar solutions in UAV-based surveillance and mapping applications using passive beam-forming technology.
