Descripción
The Radar Echo Telescope for Cosmic Rays (RET-CR) is a pathfinder experiment deployed at the Summit Station in Greenland, with a full data-taking run conducted in the summer of 2024. This experiment utilises the radar technique to search for an in-ice secondary cascade produced when the core of a high-energy cosmic ray air shower propagates into the high-altitude ice sheet.
Detecting a complementary in-ice cascade from an air shower will help verify the radar technique in nature and contribute to the ultimate goal of establishing the Radar Echo Telescope for Neutrinos (RET-N).
For both RET-CR and RET-N, we would also observe the radio emissions from the particle showers at the receivers.This includes the in-air radio emissions from the cosmic ray air shower as well as the Askaryan emissions from the in-ice secondary cascade. To effectively study the signal at the receivers, it is crucial to understand the radar signal in conjunction with the combined radio background from the particle cascades themselves. This contribution focuses on the combined study of radar and radio emission backgrounds at the Radar Echo Telescope for Cosmic Rays
(RET-CR).
