Digital Signal
Processing in Radio Astronomy –Research Experience for Teachers 2017 –Current
I run
the NSF funded
Research Experience for
Teachers Site WVU
– I taught Digital Signal Processing to high school teachers every summer using practical labs based on
GNURadio. Additionally, helped them gain an
in depth understanding
of radio telescope instrumentation
and radio astronomy by helping them build 21cm horn antennas along with their
GNURadio based backends.
– Created and maintain
the web infrastructure
to host lectures,
laboratory exercises and
lessons. Assisted
teachers
create lessons and
have built along with them a website
with lessons.
see:
https://wvurail.org/dspira-lessons/
– Assist
teachers conduct workshops virtually or visit their schools. I also lead monthly
meetings with teachers
and enthusiasts from across the country.
– I maintain the GNURadio out-of-tree module software package tailored for radio astronomy

TONE: A
CHIME/FRB Outrigger Prototype
2016 –Current
Primary PhD
thesis project
advised by Dr. Kevin Bandura WVU/GBO
– I led the building of an array
of 6m parabolic dishes at the
Green Bank Observatory to serve
as a VLBI
station to
achieve milli-arc-second
localizations of
one-o Fast Radio Bursts from a
3000+ km baseline.

Sanghavi/CV Page 1 of 5
– I assembled, tested and debugged the analog chain including antennas, low noise ampliers, RFoF transceivers.
– Integrated and debugged the digital backend including the FPGA ICE boards and the baseband recorder
server
on site. Also set up the VLBI
triggering system.
– Worked on analysis of the baseband
dump including, calibration, beamforming and cross correlation
leading
to the
localization of the triggered pulses & Fast Radio
Bursts.
– Actively perform troubleshooting and Maintainence of the instrument.

Array Network (SWAN)
with
the primary goal of gaining a wide exposure to the eld radio astronomy and instrumentation.
Investigating
the application
of hough transforms
to detect dispersed pulses.
