It is possible to derive the<br />ground footprint of a cosmic ray using the calculated electric eld strength recorded<br />by a proper set of radio antennas in a specic frequency range. In this study and<br />based on computer simulations we investigate the properties of the ground foot-prints<br />of vertical and inclined cosmic rays propagating in a location of a new cosmic ray<br />radio experiment in the Middle East. Semnan University Radio Array is a new radio<br />detection site that aims to detect ultra-high energy cosmic rays. We investigate the<br />eect of the zenith angle of a cosmic ray on the illuminated area as a result of radio<br />emission from an extensive air shower development. The maximum possible spacing<br />between radio antennas in order to be able to detect coincident events for both vertical<br />and inclined cosmic rays at the location of this new experiment is also discussed. https://ijaa.du.ac.ir/article_177_b929ba3d23b1e1987a7111abc65bd408.pdf
