MARES: A macroscopic model for the Radar Echo Telescope Contribution to ICRC 2023

Upon interaction in a dense medium like polar ice, a high-energy neutrino will deposit its energy abruptly, producing a short-lived electron plasma. The Radar Echo Telescope (RET) collaboration aims to utilize the radar technique to probe this plasma and, thus, detect neutrinos in the PeV to EeV energy range. This work presents the Macroscopic Approach to the Radar Echo Scatter (MARES) model. MARES is based on a macroscopic, semi-analytical approach and includes all the known relevant physics that will affect the radar signal. Here we show how MARES is used to investigate the effect that the ice temperature, via the free electron lifetime, might have on the radar scatter signal.
