Radio ground footprints of extensive air showers at the location of the SURA experiment

Radio stations can record dierent values of the electric eld strength from an extensive air shower induced by a cosmic ray. It is possible to derive the ground footprint of a cosmic ray using the calculated electric eld strength recorded by a proper set of radio antennas in a specic frequency range. In this study and based on computer simulations we investigate the properties of the ground foot-prints of vertical and inclined cosmic rays propagating in a location of a new cosmic ray radio experiment in the Middle East. Semnan University Radio Array is a new radio detection site that aims to detect ultra-high energy cosmic rays. We investigate the eect of the zenith angle of a cosmic ray on the illuminated area as a result of radio emission from an extensive air shower development. The maximum possible spacing between radio antennas in order to be able to detect coincident events for both vertical and inclined cosmic rays at the location of this new experiment is also discussed.
