Radio-Frequency Interference at the McGill Arctic Research Station
نویسندگان
چکیده
The frequencies of interest for redshifted 21[Formula: see text]cm observations are heavily affected by terrestrial radio-frequency interference (RFI). We identify the McGill Arctic Research Station (MARS) as a new RFI-quiet site and report its RFI occupancy using 122[Formula: text]h data taken with prototype antenna station developed Array Long-Baseline Antennas Taking Radio Observations from Sub-Antarctic. Using an flagging process tailored to MARS data, we find overall 1.8% averaged over 20–125[Formula: text]MHz. In particular, FM broadcast band (88–108[Formula: text]MHz) is found have at most 1.6%. were during summer, when degraded ionospheric conditions active research base contributed increased RFI. results quoted here therefore represent maximum-level environment MARS.

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...
متن کاملDesigning for Cooperation at a Radio Station
We address computer support for work and its coordination in one of the radio channels of the Danish Broadcasting Corporation. Based upon ethnographically inspired analysis and participatory design techniques, we propose design solutions now implemented or under implementation. We focus on cooperative aspects within and among the radio channel's editonal units, and between editorial units and t...
متن کاملExascale 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...
متن کاملStatistics 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...
