In this research, the simulation of lateral distribution function (LDF) ofCherenkov radiation was performed using CORSIKA software for two hadronicmodels QGSJET and GHEISHA. This simulation was performed for several elementaryparticles such as protons, iron nuclei, electrons and gamma quanta, in therange of energies 1-20 PeV for three zenith angles 0, 20 and 30 degrees. Aparameterization of Cherenkov light LDF was performed for that simulated curvesusing Lorentzian function. The comparison between the obtained results for LDFof Cherenkov light with that measured with Yakutsk EAS array gave a goodagreement within the distances of 100-1000 m from the shower axis.
