This Hackaday article details a DIY passive radar system built to track aircraft by analyzing existing radio wave reflections. Unlike traditional radar, this system doesn't emit its own signal, instead relying on signals already present in the environment, specifically those used for ADS-B transmissions. The system uses a nine-element Yagi antenna to capture these reflections and a computer program to compare the direct and reflected signals, identifying aircraft.
