Radio imaging spectroscopy provides a powerful tool for decoding solar eruptions and coronal structures by capturing spatially resolved radio emission, which encodes key plasma and magnetic field parameters. Instruments like OVRO-LWA, EOVSA, and the future FASR enable us to trace solar activity from its origin to the middle corona, offering insights that other wavelengths cannot. In this seminar, I will discuss how radio imaging spectroscopy can unravel the details of solar eruptions and coronal structure. By deriving key plasma parameters (e.g. electron densities, magnetic fields, and energetic particle distribution) radio observations can provide essential constraints to improve our understanding of the solar atmosphere. Integrating these data into an iterative framework with modeling will further refine our interpretation, shaping a clearer picture of solar activity.
