The Cherenkov light lateral distribution function (LDF) was simulated with
the CORSIKAcode in the energy range (1013 - 1016) eV. This simulation was
performed for conditions and configurations of the Tunka EAS Cherenkov array
for the two primary particles (p and Fe). Basing on the simulated results,
many approximated functions are structured for two primary particles and
different zenith angles. This allowed us to reconstruct the EAS events, which
is, to determine the type and energy of the primary particles that produced
showers from signal amplitudes of Cherenkov radiation measured by the Tunka
Cherenkov array experiment. Comparison of the calculated LDF of Cherenkov
radiation with that measured at the Tunka EAS array shows the ability to
identify the primary particle that initiated the EAS cascades by determining
its primary energy around the knee region of the cosmic ray spectrum.
