Radio Frequency Interference

Radio Frequency Interference

We describe the nature of the interference challenges facing radio astronomy in the next decade. These challenges will not be solved by regulation only, negotiation and mitigation will become vital. There is no silver bullet for mitigating against interference. A successful mitigation approach is most likely to be a hierarchical or progressive approach throughout the telescope and signal condit...

Radio Frequency Interference Mitigation in Radio Astronomy

Exascale Real-Time Radio Frequency Interference Mitigation

Radio Frequency Interference (RFI) mitigation is extremely important to take advantage of the vastly improved bandwidth, sensitivity, and field-of-view of exascale telescopes. For current instruments, RFI mitigation is typically done offline, and in some cases (partially) manually. At the same time, it is clear that due to the high bandwidth requirements, RFI mitigation will have to be done aut...

Statistics and Visualization of Radio Frequency Interference

This paper gives a summary of the results of a radio frequency interference mitigation project. Radio frequency interference (RFI) is a problem radio astronomers are facing increasingly in recent years. The goals of this project were: 1) investigate the cost vs. benefits of real-time RFI flagging, 2) determine ways of statistically flagging RFI by doing noise simulations, and 3) to develop a vi...

Radio Frequency Interference and Detection of Fast Radio Transients

Exploring the transient radio sky is one of the major science drivers for several upcoming and planned radio telescopes, including the Square Kilometer Array (SKA). The detection of transient signals, particularly of relatively short durations, can however be considerably hampered by the prevalent and ever growing problem of radio frequency interference (RFI) in radio astronomy. With the goal o...
