Interferometric Techniques for Impulsive Signals at Radio/Microwave Frequencies
Interferometric Techniques for Impulsive Signals
at Radio/Microwave Frequencies
- Monday April 22nd through Wednesday 24th, 2013
- Organizing by Amy Connolly and Andres Romero-Wolf
- The Center for Cosmology and Astro-Particle Physics (CCAPP) at The Ohio State University (OSU) is holding a workshop on "Interferometric Techniques for Impulsive Signals at Radio/Microwave Frequencies" in Columbus, Ohio on April 22-24, 2013.
- The last decade has seen a growing interest in the detection of radio and microwave pulses from cosmic sources using interferometric techniques. Typical radio astronomical interferometers produce long exposure images to map out brightness distributions on the sky. The ANITA balloon-borne interferometer has adapted the ideas of interferometric imaging from radio astronomy to the detection of UHF impulses and background discrimination. Current antenna arrays such as LOFAR and the LWA are using interferometric techniques for the detection of radio transients and ultra-high energy cosmic rays.
- The goals of this workshop are to bring together the developments from various fields that employ radio interferometric techniques, learn from each other's approaches to improving signal sensitivity and background rejection, and educate young researchers in these techniques. We will focus on improvements that can be made in imaging with impulsive signals such as those produced by cosmic rays via the geomagnetic effect and by neutrinos by radio Cerenkov emission.
A tentative list of topics includes:
1. What can we learn from classical radio astronomy applications of interferometry
2 Improving analysis sensitivity through different methods of signal reconstruction
3. Rejection of background carrier wave signals and human-made transients
4. Real-time applications such as using interferometry in triggering
- We encourage participation by students and seasoned experts alike.
