Abstract
Using the Auger Engineering Radio Array (AERA) as a digital radio interferometer requires about the same relative timing precision and accuracy of contrast to LOPES which is externally triggered, AERA is planned to record self-triggered events with a high signal-to-noise ratio sufficient to detect the radio pulse already in individual antennas. An event whose signal-to-noise ratio is so low that it could only be detected with interferometry will not be triggered. Thus, interferometry will not lower the detection threshold of AERA.
