Abstract

Detection of (ultra-) high-energy cosmic rays with the use of radio frequency emission from extensive air showers has been proven as complimentary to existing ground array detection techniques. Great progress has been made in the understanding of the emission processes and in their Monte Carlo modelling. These have led to experimental results, notably also at the Auger Engineering Radio Array, on energy, angular and mass composition resolution of the primary cosmic rays. Recent results are reported. The measured resolutions turn out to be competitive with existing techniques and they have independent uncertainties. Implications for cross-calibration with existing techniques and for future large-scale applications of radio detection of ultra-high-energy cosmic rays are discussed.
