GlobalSIP 2018:

Signal Detection for SETI and RFI Mitigation in Radio Astronomy

[Download the PDF Call for Papers]

The transition to digital telescope back-ends has opened up advanced computational resources for researchers to explore new parameter spaces with potential for breakthrough discovery in astronomy and the Search for Extra Terrestrial Intelligence {SETI). The flexibility of those systems will additionally enable the community to address the major challenges currently faced in radio astronomy, such as the mitigation of Radio Frequency Interference, the accurate calibration of next generation instrumentation, or even novel methods for data mining and information extraction.  The proposed symposium will provide researchers a platform to overview the state of the art in radio astronomy instrumentation and algorithms, and to define and put forth the challenges currently faced and expected to arise in the near future.

Signal Processing Methods for Mitigation of Radio Frequency Interference in the Era of Real-Time Astronomy

Modern signal processing methods for mitigation of radio frequency interference (RFI) in radio astronomy are enabled by off-line processing of data recorded with high time/frequency resolution. The radio astronomy community is now making its first tentative steps toward an era of real-time data reduction in which RFI mitigation is nominally performed on-the-fly in the limited interval during which data with high time-frequency resolution are available. This presentation provides a brief overview of RFI mitigation methods in the context of this "post-observation" versus "on-the-fly" dichotomy. Also considered is how emerging technologies such as heterogenous computing, machine learning, and dynamic spectrum access might play a role in modern RFI mitigation systems.

Steve Ellingson is an Associate Professor at Virginia Tech in Blacksburg, Virginia in the United States. He received PhD and MS degrees in Electrical Engineering from the Ohio State University and a BS in Electrical & Computer Engineering from Clarkson University. He was affiliated with the US Army, Booz-Allen & Hamilton, Raytheon, and the Ohio State University ElectroScience Laboratory before joining the faculty of Virginia Tech, where his work includes the development of meter- and cm-wavelength instruments and observing techniques. Ellingson is the author of Radio Systems Engineering (Cambridge University Press, 2016) and the open textbook Electromagnetics Volume 1 (VT Publishing, 2018).

Submissions are welcome on topics including:

Paper Submission

Prospective authors are invited to submit full-length papers (up to 4 pages for technical content including figures and possible references, and with one additional optional 5th page containing only references) and extended abstracts (up to 2 pages, for paper-less industry presentations and Ongoing Work presentations).. Manuscripts should be original (not submitted/published anywhere else) and written in accordance with the standard IEEE double-column paper template. Accepted full-length papers will be indexed on IEEE Xplore. Accepted abstracts will not be indexed in IEEE Xplore, however the abstracts and/or the presentations will be included in the IEEE SPS SigPort. Accepted papers and abstracts will be scheduled in lecture and poster sessions.
