radio ground footprints of extensive air showers at the location of the sura experiment

Radio stations can record different values of the electric field strengthfrom an extensive air shower induced by a cosmic ray. it is possible to derive theground footprint of a cosmic ray using the calculated electric field strength recordedby a proper set of radio antennas in a specific frequency range. in this study andbased on computer simulations we investigate the properties of the ground footprintsof vertical and inclined cosmic rays propagating in a location of a new cosmic rayradio experiment in the middle east. semnan university radio array is a new radiodetection site that aims to detect ultrahigh energy cosmic rays. we investigate theefect of the zenith angle of a cosmic ray on the illuminated area as a result of radioemission from an extensive air shower development. the maximum possible spacingbetween radio antennas in order to be able to detect coincident events for both verticaland inclined cosmic rays at the location of this new experiment is also discussed.
