Hello Gnu-Radio.
We’ve been working to get Radio Astronomy working
reliably in Gnuradio. A number of
folks have made some excellent contributions to this
area.
Kevin Bandura and I have been working with the Green
Bank Observatory to develop
horns for observation of the spiral arm structure of
the Milky Way. The
The latest Gnuradio spectroscopy and event detection
graphs are in the West Virginia University
contributions to GitHub; i.e.
Follow the instructions to install the graph and
build the code.
The documentation on the graphs are at:
There are some configuration files tuned with Radio
Astronomy, but the event detection
code (written in C++) should have a wide
applicability for detection of glitches in your
time series of samples. Attached is an image of
radio transient detected in February 2019,
that has the characteristics consistent with a
cosmic ray flash, that is part of our science
target.
The radio astronomy graphs have been used with
Airspy, Airspy-mini, the various RTLSDR dongles, PlutoSdr and
LimeSdr
hardware.
So, one of the problems with "singleton" events is that they aren't
unambiguously "the thing that you're looking for". Glitches from
Someone in Gnuradio pointed out that a lot of our
code was concerned more with post process of recorded data
than truly part of gnu radio. Now, all the
post-processing code, and some documentation is obtained with
Finally, we’d like some help with one aspect of
event detection.
Right now we’re limited to about 6MHz bandwidth (12
MHz samples) with the existing hardware/software.
We’d like to update the Pluto firmware to perform
this task, while simultaneously allowing Gnuradio to
run on the host pc/single board.
The code is already complete, but not ported to the
PlutoSdr. Anyone interested in collaborating
on this project?
Thanks
Glen Langston
