Radar Echo Signals for RET-CR

The goal of the Radar Echo Telescope (RET) collaboration is to detect ultra-high-energy (UHE) neutrinos via in-ice radar techniques. To this end, the RET collaboration aims to demonstrate the radar echo method in-situ with the Radar Echo Telescope for Cosmic Rays (RET-CR) experiment, located near Summit Station, Greenland. RET-CR utilised secondary in-ice particle cascades - generated by high-energy cosmic-ray air showers impacting the ice surface - as a test beam for the radar method. In this work, radar signals within a RET-CR detector configuration have been simulated using the semi-analytic simulation package MARES. The effects of different radar echo features on signal observables, including amplitude and frequency, have then been explored and linked to properties of the progenitor cosmic rays.
