Rejection of Transient Noise at the Auger Engineering Radio Array — •Christoph Welling, Christian Glaser, Martin Erdmann, Florian Briechle, and Raphael Krause — III. Physikalisches Institut A, RWTH Aachen University

One of the challenges that radio detectors for air showers face is contamination by pulsed radio noise which may coincide with a cosmic-ray event. These noise pulses can originate from a multitude of sources, such as power lines or radiocommunication devices. In order to perform reliable cosmic-ray measurements it is necessary to be able to identify and reject such noise. In this talk, we present rejection methods based on the timing, shape and polarization of the measured radio pulse as well as the positions of the radio stations with a detected signal. The rejection algorithms were tested and optimized for use at the Auger Engineering Radio Array (AERA) in Monte Carlo studies using air shower simulations combined with a full detector simulation including on-site recordings of radio noise.
