Variable amplification input zero delay least mean squares adaptive filter for RFI suppression in AERA radio detectors of cosmic rays

Popis výsledku v původním jazyce

Extensive Air Showers (EAS) generate radio emission mainly in geomagnetic and charge excess processes. The Auger Engineering Radio Array (AERA) focuses on the coherent radio emission, generated in the frequency range of 30 - 80 MHz. However, this range is contaminated by human-made and narrow-band radio frequency interferences (RFI). At present, AERA uses a non-adaptive IIR filter tuned to the four strongest narrow-band carriers. The efficiency of the RFI suppression is very good, but for only well-known sources. In the near future, a 200 MW solar farm with a 250 kV power line is planned to be built in the Southern part of the Pierre Auger Observatory. The non-adaptive filter will probably not suppress the much more sophisticated RFI spectrum coming from high-power low-to-high voltage converters.
