The author demonstrates how a barely audible propeller plane’s Doppler curve in a video’s background audio can be combined with ADS-B flight data, CPA time delays, silence filtering, and other layers of screening to narrow millions of candidate points down to an exact location, showcasing the powerful potential of audio signals for geolocation.
DyRAD presents a radar novel view synthesis method for dynamic driving scenes that models static background and motion-tracked dynamic point reflectors to render complete range-azimuth-Doppler tensors, using a fixed analytic point-spread function to enable zero-shot sensor-configuration transfer and outperforming baselines by a wide margin on the RADIal benchmark.
