Description
High-energy neutrinos act as cosmic messengers, pointing back towards sources in the
universe. These particles have an extremely low flux, so radio techniques can help us to
probe large volumes and thus increase detection rates. The Radar Echo Telescope (RET)
aims to detect neutrinos by reflecting radio signals from the ionized trail left behind by
the cascade. This is done in ice, as it is a much denser medium than air and thus more
likely to reflect the waves. The first iteration of the RET, the Radar Echo Telescope
for Cosmic Rays (RET-CR), has been deployed in 2023. Calibration measurements
were done for RET-CR, using a metal rod as a reflector instead of air showers. We
studied this data to understand and check properties of the signal, including the relative
amplitudes and timing differences between the receiving channels, and comparing them
with simulations and theory.
