First results of air target detection using single channel passive radar utilizing GPS illumination

The paper presents preliminary results of moving airborne target detection done by a passive radar demonstrator exploiting GPS (Global Positioning System) L1 band signals for target illumination. The demonstrator is built using a single antenna concept and digital reference signal reconstruction. In the paper both the potential advantages and challenges of GPS-L1-based passive radar are identified. A detailed description of the experimental setup including its hardware components and utilized signal processing algorithms is provided. The obtained results are presented and discussed, allowing an evaluation of the feasibility of building an operational GPS-based passive radar.
