Multi-detector observations of individual air showers are critical to make\nsignificant progress to precisely determine cosmic-ray quantities such as mass\nand energy of individual events and thus bring us a step forward in answering\nthe open questions in cosmic-ray physics. An enhancement of IceTop, the surface\narray of the IceCube Neutrino Observatory, is currently underway and includes\nadding antennas and scintillators to the existing array of ice-Cherenkov tanks.\nThe radio component will improve the characterization of the primary particles\nby providing an estimation of Xmax and a direct sampling of the\nelectromagnetic cascade, both important for per-event mass classification. A\nprototype station has been operated at the South Pole and has observed showers,\nsimultaneously, with the tanks, scintillator panels, and antennas. The observed\nradio signals of these events are unique as they are measured in the 70 to\n350 ,MHz band, higher than many other cosmic-ray experiments. We present a\ncomparison of the detected events with the waveforms from CoREAS simulations,\nconvoluted with the end-to-end electronics response, as a verification of the\nanalysis chain. Using the detector response and the measurements of the\nprototype station as input, we update a Monte-Carlo-based study on the\npotential of the enhanced surface array for the hybrid detection of air showers\nby scintillators and radio antennas.\n
