Solar System Technosignatures: Classification, Multimodal Detection, and Mission Roadmaps

To the point

Solar System technosignatures are observable signs of advanced extraterrestrial technology in our own solar system, detectable as artifacts, anomalous trajectories, unusual spectra or emissions, or other imprints across radio, optical, infrared, radar, and in-situ measurements, and researchers such as Davenport, Ellery, Wright, Lazio, and Haqq-Misra advocate a multi-modal, data-driven approach that uses machine learning to distinguish genuine signs from natural or human-made signals and to guide future missions and observatories.
