Description
The Radar Echo Telescope for Neutrinos (RET-N) is a future neutrino experiment that aims to observe the cosmic neutrino flux at the highest energies ($> 10^{16}$ eV) utilising radar. Radar allows for determining the position, speed and direction of any radio-reflecting object. High-energy neutrino interactions in glacial ice induce a particle cascade of energetic secondary particles, which in turn create a dense trail of free ionisation electrons. This trail can serve as a short-lived macroscopic radar target for neutrino detection. Therefore, radar is a potential cost-effective radio-based approach for detecting these highly energetic cosmic particles. In this work, we discuss the rich signal properties of the expected radar return from neutrino interactions in ice and how the resulting global description of these features can help develop reconstruction methods and detector design for RET-N.
