Abstract

RFI mitigation algorithms aim to remove this interference and improve the signal-to-noise ratio of any detectable transient, but with the growing number of techniques, selecting the most appropriate methodology for a given survey can be problematic. Currently, the strategy is decided by the astronomer, which is not scalable for real-time systems planned for next-generation telescopes such as the SKAO telescopes. We have tried to explore the algorithm selection problem by simulating several RFI environments along with pulses injected into a white noise filterbank file, which is then cleaned using each of a number of RFI mitigation algorithms and run through a single pulse search pipeline to analyse the recovery of the injected pulses. We examine the recovery of the known single-pulse parameters with an emphasis on a number of realistic corner cases. In addition to this, look for some solutions to the identified problem as well.
