RFI mitigation for the Effelsberg-Bonn HI Survey (EBHIS)
A new L-band 7 feed array at the 100-m telescope is used to perform an unbiased, fully sampled HI survey of the whole northern hemisphere - the Effelsberg-Bonn HI Survey (EBHIS). The use of state-of-the-art digital Fast Fourier Transform spectrometers based on FPGAs - superior in dynamic range an...Tags: "instrumentation and methods for astrophysics", effelsberg, hi, ebhis, rfi

A LOFAR RFI detection pipeline and its first results
Radio astronomy is entering a new era with new and future radio observatories such as the Low Frequency Array and the Square Kilometer Array. We describe in detail an automated flagging pipeline and evaluate its performance. With only a fraction of the computational cost of correlation and its us...Tags: rfi, lofar, ska, sumthreshold, arxiv

A method of detecting radio transients
Radio transients are sporadic signals and their detection requires that the backends of radio telescopes be equipped with the appropriate hardware and software to undertake this. Observational programs to detect transients can be dedicated or they can piggy-back on observations made by other prog...Tags: transients, rfi
